It's always been like that. I got that screen a few times over a year ago. I think they may be enforcing it more now with all of the spam being posted lately.

I miss the old funsubbbstance :, (

Yeah yeah have been doing it alot recently

Yeah I was gonna go bat shit insane on his haters but it wouldn't let me

If I post a picture I have to wait like an hour before it "gets enough likes"

It stops the useless spam to a certain extent, so I'm not too upset about it.
