Just because the RP Forums are different doesn't mean it is more useful to delete from there than anywhere else. What TV Tropes has is a memory issue, which means that we've got to free up memory. Save for your initial point, I could list the same points for other forums. OTC and IJAM don't really add to TV Tropes mission statement any more than the RP forums do since they are neither talking about media specifically (which would be the domain of the various media subsections) nor involved with the actual running of the site itself. Few topics in general are really going to be revived after a year and a half and even if there was a retread of material, it would likely be better to have a new topic anyway in most cases. However, I can actually mention a good reason why topics in the RP subforums would be revived and why pruning it may be a little more complicated than other forum sections.
As you've mentioned, there are three RP subforums... the RP subforum, the RP Discussion, and the RP signups... Because each RP has one topic in each section, the mods need to be sure that they aren't deleting only parts of an active RP. By its very nature as a signup forum, the topics in the RP Signups are going to be dead most of the time since it's for just posting signups and getting approval to enter. A very active RP could have a very dead RP signup because no new people are entering it.
Now, I'm not asking that you avoid cleaning out the RP Forums, since even I'll admit that it needs some cleaning, but if it must be done, I feel it should be done with caution and respect to the various RPs within. They might be the most prolific posters on the board and make little edits to the tropes themselves, but an RP is really just a collaborative writing session with a few rules and regulations to keep it somewhat controlled. The rest of the forums might be more active in creating and editing tropes, but the RPers are the ones actually writing stories and putting those tropes into practice. Sometimes, I feel people who don't visit the RP subforums miss that.
Either way, I've said my speech, and would be glad to help you in finding which inactive RPs to purge should the purging of Yack Fest prove ineffective. We over at the RP subforums do care about the rest of the site, we just enjoy writing stories and using tropes rather than editing the site and creating them.
