There are certainly some comments that I made that I've later regretted, but not that many. I've commented on the work itself but I never have gone out of my way to personally attack a writer. Obviously, there's a difference between stating what you like/don't like and flaming the author. There should be a rule in the ToS that allows mods to delete comments that do that. I took a quick look through the guide, but didn't see anything.
What I lamented (and I've said this) is that the cuck thread became the main hub of the story for months. That is, it was the only thing getting updated and discussed, which was disappointing. That's what I meant. People will obviously write what they want, but I like engaging with branches, even if I don't like them.
And censoring threads is absolutely more insane than some person leaving a negative review. It seems a little head-scratching to argue otherwise. I've left plenty of legitimate criticism that address character continuity, motivations, and rationality. As for tags, I believe it was duskford that told me that Cloontang doesn't really keep up with the site/story anymore. So I could try your suggestion but I'm skeptical as to what affect it would really have. I don't know why this topic was made either or what the purpose of it is.
