The greater concern lies in the fact that this change led to fewer campaigns, less traffic into the forum,
You have to post a stat to back up your claim, I have always said before that Bitcointalk's massive traffic comes from organic traffic created from thousands of discussions that are indexed by search engines, and with thousands of backlinks Bitcointalk gets massive respect from the search engine
and the fact that energy is diverted from everywhere else in the forum to gambling discussion, since most of these signature campaigns (including the one that I'm on right now) require their members to post a couple comments in the board. The latter's not necessarily a bad thing as more people means the gambling board can finally get its break from stupid users creating shitposts and shitcomments but at the very same time this takes engagement out of the more important parts of the forum in my opinion. We may not notice it right now but as more gambling sites push for advertisement here it's going to be more and more apparent.
Traffic does not come from gambling posters and gamblers alone some discussions about Bitcoin and other subjects that are years older that able to pull traffic for Bitcointalk.
Pretty sure theymos got's something up his sleeve as what many people here have thought since you can't just issue a massive change like this without weighing in the consequences, but at the same time it's better be good lol.
I'm pretty sure Theymos knows what he is doing he is the Admin he has the comprehensive traffic stat of the forum, apart from the public stat here
