The bot situation is so bad right now that I have to stop myself from automatically blocking new followers. I completely mislaid the previous post about this I made so here's a new one:
Please put something in your bio, change your pfp, reblog a few posts, show some sign of human life. This lets us old and jaded tumblrites know that you are, in fact, a person, and not a spam or porn bot trying to get engagement in order to appear more legit.
If you are attached to your default icon, here's a picrew that will help you add signs of humanity to it without completely abandoning your cute little geometric buddy:
It really doesn't take much to let people know you're a real human being, and it will save you from the disappointment of being blocked by the folks you wanted to follow before you even know what you're doing here.
Welcome to tumblr. It's a blue hellsite. You'll love it. Just please fly your human flag so we know to welcome you and not to zap you!
