what will happen if all signature campaigns end
What will happen? Shitposters like
you..
I was wondering whether I should post something like that as soon as I've read the OP, and the following replies, but nicely done. OP got roasted.

The forum loses money by allowing signature campaigns here. Most businesses/projects don't bother buying ads when they can have their signatures plastered all over the forum for free as opposed to buying one tiny, barely noticeable ad slot.
Which is why signature campaigns need to be heavily regulated/moderated or completely shut down. I agree.
There are a lot of people who earn money from the signature campaigns and am sure that it's going to be very unbearable for them when that happens and I really don't see signature campaigns ending as long as there is bitcoins in the system. So that's nearly impossible.
Stop spamming with your bullshit, idiot.
