Colin won't be 'demoted' regardless of the fact he has become a meme for the cringeworthy 'anti-establishment' / 'our voices should be heard!' trend. I went over the last few pages just to check and as a forum moderator Colin isn't doing anything that he shouldn't be. Well, with the exception of that thread where its entire purpose was to highlight a racial slur in an image (lets be real) ...that one should have been outright deleted.
I don't think that there's any reason for anyone to post here in an abundance of junk. If anyone is leaving it is because the overall quality is dropping and being replaced with spam and pointless threads. This is not a consequence of Colin being a moderator, it is because of people desperately trying to be funny or edgy. Maybe that's just the community we've got here now, but it doesn't mean that these posts aren't going to be removed.
Just like in-game, if you don't do anything that warrants moderating your stuff won't get moderated. I'd actually say he's moderating more consistently than they do in-game, but that doesn't mean anything. If you think this is bad you really need to go try posting on some of the other Graal sites.
