Not exactly. The last For Sale section changes happened a year before the forum was sold. And the changes in general started about 2.5 years prior. You've commented about sales-related issues in the past (I just checked some of the archived threads we have) - you just may not remember them.
There were, unfortunately, a set of (now former) members who schemed & abused the For Sale section nearly 24/7. Constantly bumping threads, editing, removing, taking massive pre-orders & skipping out, running multiple accounts, smuggling Buce, bumping, commenting to drive up views, skirting limits, more bumping, etc. It was non-stop BS for some of them. They treated it as a free-for-all with no limitations. Some of them still try it. Some of them are no longer in the hobby.
Most of them, after being kicked off the forum - occasionally for illegal activity, took to social media and other outlets to whine and complain about moderators (me in particular because I don't have patience for con artists like h4n and msnikkistar). They were fairly popular on the forum, so their sob stories were gobbled up. Was just fortunate for them that we, as a policy, didn't spill the T about the shenanigans they were up to. Because some of them would have for sure disappeared into the ether for eternity. While some could have gone to jail for the crap they were pulling. It was mind-boggling.
Now it's locked down. For Sale section can't be accessed unless you're using the desktop version of the site (this can be done on mobile) and is inaccessible via third-party applications like Tapatalk. We don't want the forum to be an open sales paradise or even sales-centric. Information sharing comes first. Everything else is just an added bonus.
It was a change that happened when it was sold - I'd never seen or heard of any issues myself.
Participation on forums in general has bottomed out because of the transition to social media. Many want instant gratification and aren't interested in substantive discussion. In a hobby like this that's frequently treated as a momentary blip in life? Folks flock to the quick and easy. It's generally the lifers who stick around sites like this.
There are also folks like me who see Facebook as the scourge of humanity. I like instant gratification but am not willing to give up ownership of my data and definitely am not interested in the non-stop bigotry and personal attacks. At least with this forum, there's almost no data collected or stored. Certainly no details about shopping habits, likes, that sort of thing that can be tied to you as a person. It's a place where a hobby can be a hobby without the bombardment of everything else in life - a bit of a slow-paced escape.
