During my own copyright battles I have had the opportunity to work with dozens of different hosts and providers. My experiences have been extremely varied in nature, ranging from outright pleasant to deathly abysmal.

Please note that all of these ratings are based upon my personal experiences. Your experience may vary and, if it does, please contact me. I'd like to hear about it. Also, since my other site (the one that's plagiarized from) is a poetry/literature site, please note that most of the places I list will be similar in nature. I will list other sites as I have experiences with them or receive reliable reports regarding them.

Allpoetry Network (Form): The Allpoetry network has a network of great moderators, at least a few of which are always on, a strong copyright policy and an easy to use abuse form on each page. The only drawback is that you have to register for an account before submitting a complaint. A small matter though and it allows the moderator in charge to contact you via PM. Always responds to requests within fifteen minutes. The best.

Livejournal.com (Form/DMCA): Even though LJ requires a DMCA notice with each complaint, they make it easy. You're able to go through the usual abuse process and follow a step-by-step form to file a complaint. Once submitted, complaints are handled quickly and decisively.

GreatestJournal.com (Form/DMCA): Similar to LJ in style, GJ takes only a slightly different approach. They're one of the few hosts to post their copyright policy at the foot of each page and they make it very clear what is expected of an infringement complaint. Once submitted, complaints are handled very decisively and follow up is excellent. They clearly take these matters very seriously and don't hesitate to take action.

Angelfire/Tripod/Lycos (Email/DMCA): Lycos has improved greatly since I first wrote about this site. They now accept email complaints, so long as you use the account dedicated to their agent (PDF) and have improved their already fast response time. They've shown that they take matters of copyright infringement very seriously and have worked hard to improve their handling of such matters. I now see them as a very solid citizen.

Esmartstart.com(Form/DMCA?): Treats complaints very seriously, perhaps too seriously. Almost immediate takedown of pages found to be infringing. Clearly has no tolerance for plagiarized or otherwise stolen works on their servers. However, there is no contact with the individual filing the complaint and a very ambiguous policy about what is required to file one.

Campuskiss.com (Form): Requires registration before reporting someone to “big brother”. A Canadian company, not bound by the DMCA, a basic copyright complaint is all that's needed. Such complaints are handled quickly but with little zeal and no feedback is given to the complainant, even though the site's email system. They get the job done but not much more.

DeviantArt.com (Email): DA has never failed to take down infringing work, they don't require a DMCA notice as of yet and handle all matters very swiftly. However, there seems to be some inconsistency in how copyright matters are handled, some are treated very sternly and other, almost identical, cases much more lightly. Also, no feedback is offered after a complaint is filed. Would easily be a hero if not for those two things. (Note: Just discovered that, for whatever reason, DA can not delete posts to user journals. Such abuse results in the user being banned until the work is removed.)

Myspace.com (Email/DMCA): Myspace follows the DMCA to the letter, removing all works that are reported to be infringing with a properly-formatted DMCA notice and responding quickly to such notices. However, don't expect Myspace to go above and beyond the call of duty. Infringing accounts are rarely, if ever, shut down and everything about their response is geared toward only doing what is absolutely necessary. Even their reply, which lets you know the infringing works are removed, drips with legalese. Still, given the size of Myspace, 64 million accounts and growing, even minimal compliance is a herculean feat and far more than adequate to help copyright holders protect their works online. 

Friendster.com (Email/DMCA): Finding out how to submit a complaint to Friendster is a unique challenge. The site has not registered with the U.S. Copyright Office and all of the information on the site itself points to a vague support page that can only be accessed by members. While one can easily sign up for the site and file a report that way, others need to perform a whois search to find a valid email address for the admins. However, once you email a proper DMCA notice to that address, the response is very fast, usually within a few hours, and very friendly. I'm giving Friendster Citizen status on a probationary basis in hopes that the site will update its records and become fully DMCA compliant. It is obvious that the people behind the scenes are very interested in fighting copyright infringement and I would hate to relegate them to villain status on account of what could be a technical error.   

Xanga (Mail/DMCA): If you can get a reply out of Xanga, you're doing more than I. After nearly ten letters, six of them sent through the abuse form, I am yet to get a single reply back from Xanga. Combine that with an unusable phone number and a false fax number and it seems the only way to contact them is via snail mail. While every company is free to set their own policies, some level of communication is generally expected. It's even harder to accept because Xanga does such a good job explaining copyrights to its users, only to give the silent treatment to those that find infringements of their work on the Xanga servers. They are, without a doubt, the least cooperative company I've had the displasure of working with. 

Microsoft (Email/DMCA): Microsoft was, and to my knowledge is, a huge advocate of the DMCA. However, when it comes to actually following the more unpleasant parts of it, Microsoft is downright hypocritical. I've notified MS of three different plagiarism incidents and twelve days later. One was removed ten days after the notice was sent and the other two, including one fifteen days old, remain up with no dialog from the certified agent. Companies a small fraction of their size have proved more capable in this area.

MyOwnJournal.com (Email/DMCA?): MOJ clearly has no respect for any violations that take place on their servers nor any desire to stop them. The only account set up to receive complaints of abuse, of any abuse, bounces mail back. I looked up an admin contact through a whois search and got a reply saying the matter was “being looked into”. However, four days later, I've heard nothing back. A haven for Internet villains of all types.

OpenDiary.com (Email?): It's hard to imagine a much worse host than OpenDiary. Quite literally, every account used to contact the domain bounces back, including the abuse one and the one listed with their domain registration. This is flagrant disregard for their users, other copyright holders and their own servers. I've reported them to ICANN for invalid Whois information and hopefully will get a valid email address out of this.
