For those unaware because staff isn’t saying it
Tumblr was deemed too full of inappropriate content to be allowed to be downloaded from the app store.
It has this “inappropriate” problem because of rampant porn ad bot accounts. The old solutions were bots to detect image sets with nsfw content, the automatically enabled safe mode, tag filtering for mobile, and wide takedowns of nsfw bots based on words used (that’s why their messages are full of numbers and symbols, to evade this)
Tumblr released their own bot supposedly capable of wiping the ad bots, but it’s taking down many popular blogs, possibly due to sheer amounts of posting or sheer amounts of ad bots in their notes. This bot was likely rushed to be put out.
You are more likely to be accidentally flagged if you post external links, as well. If your acct is taken down you CAN get it back, but it’s a pain. E-mail tumblr support for help with this. It takes down side blogs with the main ones.
I’ll be halting posts for about a week or until this problem is fixed.
Know what’s incredible about this? They literally did not have to design a bot to attack other bots. I bet they could have ended almost all of this bot problem by limiting the number of side blogs people can create off of one email to something reasonable like “10” and make each new URL created require a captcha entry.
It’s like this site was deliberately set up by a spambot enthusiast, it even will randomly generate a new untaken URL for you. (That’s why a lot of spam blogs have names that are like AdjectiveAdjectiveNoun, because that’s what Tumblr’s URL generator does.)
