I've been on DA since high school and it really used to be a much better place. I never really participated in the community apart from comments and likes but overall talking to others was fun.
I was gone for a few years and when I came back it was as all of you said - in no way one could discover new art because it was all flooded with porn, fanarts and mobile photos... At least the porn could be blocked but then you had a wall of censored images XD So I gave up discovering new art there 
I wish they divided the whole website into parts for fanart, selfies AND original art - this way we could be happy in our little "original art" section 
Except being stalked one time (one of the reasons I left for all those years), I've only read about people getting hate, but I admit it still scared me - one of my picture some years ago became featured and got hundreds of comments and being a shy person I'm just too scared to read through them >.<;;;
I want to share a funny thing: recently I've been moving my old stuff there into scraps so that my gallery would be more representative of what I do now, and I've noticed that the images in my scraps have much more favs than my recently uploaded pictures!
It's because the scraps are from my first years there, where the community was nicer and getting noticed was easier.
Now I'm just using it to post random stuff when I remember to, and quickly leave again.
Exactly. I hate it when people focus only on popularity 
Actually, I found that quite hilarious, it would be cool if it happened on April 1st XD
And yeah, I've never heard of staff being so devoted to their website as Tapastic. So let's enjoy being here - we don't have to worry about DA when we have Tap, right?
