"They are not under any obligation, however, to allow anything to be posted by anyone at any time. Quite the contrary, they are often under a number of legal and other obligations to their investors and business partners to specifically restrict certain kinds of information. And, even if they weren't, they pay the server bills, they buy the hard drives, they employee programmers and designers to bring this service to us; they can define their own rules, and they do."

Under normal circumstances, I'd agree with you 100%. But closing down an Off Topic forum, for posts that were, well, Off Topic (vs the TOS mentioning banning individual people - not closing down an entire forum - for posting personal attacks; which were alleged and continued after the forum was closed) seems a tad overbearing and, IMHO, not in compliance with the agreement made at the time of membership (aka the TOS).

AFAIC, R'osity made their decision and I'm fine with it, but it doesn't mean that people have to agree with the reasoning behind the decisions. In fact, The Den emerged, more or less, as "OT Lite" a few weeks/months later because there was, is, and always will be a desire to communicate information that is not necessarily topical to the theme of the forums/site.
