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?
If you are really annoyed with signature campaign, you will disable them. Same thing if you are annoyed with some users, you can always put him on ignore. But it's easier to QQ and complain about it rather than spend 1 minute and solve it.
What if i am accessing the forum without login in?
If that really bothers you, log in. Or is that too hard too?
Why is not the opposite?
If i want to see the annoying spamming signature i turn the signature ON.
So just because you are annoyed with signatures, forum should cater to your needs and disable everything on default so you don't have to spend 1 minute of your precious time disabling them. Sure.
And this is another reason why most of the activity is moving to chats, like telegram or discord.
There is no signature on those chats.
No one is moving to those because of signatures. They are simply different things, that serve the different purpose. Forums are generally less popular than they were 10-15 years ago, that's true. People simply have more options to communicate, and younger generations prefer something faster.
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.
I don't know about Discord as I am not active there enough, but Telegram does have "Scam" mark. Accounts get tagged with that when they get reported enough times, I don't know how you missed that if you are active enough on Telegram. After all, Telegram is cesspool, plagued with scammers.
