Go ahead Tumblr, purge our pages, ban the artist and turn the rules against us... IT MEANS NOTHING! when the dust settles, the only remain thing will be porn.

So the owners of Tumblr walked away with 1.1 billion, Yahoo walked away with 4.4 billion and tumblr got absorbed into Verizon Media Group and you think everyone moving to New Grounds is some sort of victory? Tumblr is a write-off. You've won nothing.

It's great that Tumblr is dying, but Twitter is definitely a much worse place for all these artists to go to.

It was a porn site but they decided they wanted to be a site for bigots instead.

@Wind-Pet
Before December 17, It's a porn site that's trying to ban pictures of loaves of bread, sand dunes, and anything else that's vaguely flesh coloured and/or curvy.

Kinda disappointed that hentai foundry was on bottom instead of pornhub. It's pretty crazy but apparently they've got stuff where artists can be paid for their work too.

Base +5, 69y +7, SciFiMisc +6

Everyone should look to host on websites outside of america or the eu thanks to FOSTA; america's anti sex trafficking law and article 13, EU's crap copyright filter.

Base +19, Canis_Crazy +6, roadkillfish +4, tadpolegaming +4

The site itself sucked but there's art stuck on there that will be lost to time.

Also Baraag.net

Goodbye, Tumblr. You had some great porn and you contained the madness from infecting us all.

LOL Tumblr's so retarded for them to put a strict "no porn" policy onto their site because of the degenerate minority posted CP. What they need to do is to police their site properly and have a report button so they can punish the ones who posted that disgusting CP. But no, they have to be idiots. All that will be left will be a bunch of millennial far leftest infesting that site much like how nazis took over gab.ai.
