But signatures are a problem, why do i need to go to settings and block the signatures or the user because their signature is spamming and annoying?
What if i am accessing the forum without login in?
There is no doubt that you are completely obsessed with the idea that signatures are the reason why someone wants or does not want to be on this forum - so I can also ask you how you deal with ads on television, radio, internet or billboards? There are others who think that signatures should be completely banned - but I don't see how that would improve the activity of the forum, unless you think that in that case thousands of people from other social platforms would suddenly start using this forum?
Also i notice that some treads there is a warning saying that the creator of the post is a scammer, i never seen that on Discord or Telegram.
Take a look at ONION tread, there is a big warning, but there is no warning on their Telegram.
First you need to get acquainted with all the possibilities and rules of the forum, and then you will learn that this forum has its own ways to combat scammers, and one of them is to create just such warnings - which of course has nothing to do with other social networks or forums where someone advertises in any way.
