I've been reefing off the grid for quite a while (for probably the last 4-5 years). Just recently started getting back into following the forums and it seems like the online culture has changed in the past several years. I haven't really been on ReefCentral since probably around 2008, and now it seems like the attitude is really different than it used to be.
It would appear that a bunch of other forums have popped up (or maybe they were already there and are now just appearing on my radar...), and it seems like the moderators have gotten really aggressive. I also noticed that they started dropping the ban hammer for stupid dumb stuff (banning Melev back in 2010.... I'm really behind on the news....), and enforcing stupid rules about certain external links, items in signatures, etc.
Did something happen that forced them to start reacting this way, or was it gradual over time?
