Nothing against you. I've just seen a lot of these over the years and I was mostly throwing in my two cents in the thread of things I don't like to see.
Which brings me to my other thing. If I don't like something then I try to counter it with something positive. I try to be a middle of the road person and understand where people come from, even if I don't agree.
Nothing wrong with venting, I just tend to do it with a closed circle of people, rather than an entire forum.
So I say, let the sub-4-subbers do their thing, it's really not hurting anyone. It's okay if people want to promote their work that their excited about. If I really don't want to see these things...I mute the category.
As for the Collab threads...any artist worth their salt will not bite, as much as it's annoying, it won't stop, because most of these posters drop their thread and dip out, they're likely doing it in a bunch of other places as well, so they'll have no regards for the rules whatsoever. So there's really no point in trying to make a system, because... they're not interested in the system. Easier just to mute the category.
@noenoh kinda nailed it on the head. It really is detrimental for newbies to see the gatekeeping, especially for younger people who're just making comics for fun, it sucks the fun right out of it.
So... that's just how I see things. We're all different people with different motives and views. I'm really not trying to dump on you here @sorible. Just expressing my viewpoint.
(While I was typing this out, @VibrantFox pretty much summed it up nicer than I did XD. The silver lining is something I always try to see.)
