I tried to set up a SMF forum on a Wordpress site a couple of years ago and did nothing to advertise it. Within days - literally days - I had hundreds of accounts posting links to viruses and stupid things to buy. There were no other users than the bots ... sometimes replying to each other, lol. I nuked the thing from orbit. It was the only way to be sure. Moderation would have been a 12-hour a day job.
So yea, this forum is built on old tech from the 2010's that is unprepared for the onslaught of simple bots, much less the coming AI bots which
will hopefully destroy social media as we know it.
I think the $5 fee to join is an amazing experiment. THAT will filter out the bots, guaranteed. But it will also raise the ante for the people willing to do things that will get themselves banned, like flame warring or incivility. Maybe that argument isn't worth it if setting up a new account will cost five bucks!
Also, AI is well past the Turing Test and the MMM Forum is instituting this cover charge just as all other social media services are about to be inundated with bot accounts that cannot be identified by either machine or human mods. Thus the old timey MMM Forum might become the last place on the internet where you can rest assured you are chatting with a fellow human being. And not just any human being... not the trolls of Reddit for example... but people who are motivated to be here.
I'm sure the rationale for the cover charge is that the forum will need money for upgrades eventually, OR maybe MMM or the Mods are just tired of managing it and aren't afraid to let it die. But I can see things going another direction, and the forum becoming an oasis of quality in a desert of trash data.
It could actually become
more popular among humans who are not too cheap to spend a fiver as every other service becomes 99.999% AI-generated within the next couple of years.
My only concern is for the... Cheap Bastards. Spending $5 on a social media account is hard to justify. Thus the voices of the hyper-frugal could be slowly extinguished on the MMM Forum, and eventually the internet (as there is no incentive for bots trying to sell stuff to advocate frugality). Perhaps the almost ad-free experience will be worth it for frugalistas.
