Once again, I am BEGGING people to realize that tumblr tags are a filing system and not a visibility metric.
One does not come to tumblr to tag-spam for notes and get popular. There is no algorithm here. There is no monetization here. There are no influencers here.
This is where every other social media system comes to die. And we cackle and roast marshmallows on the pyre like the gremlins we are.
If you tag-spam to get your post seen by as many people as possible you are actually getting blocked by a bunch of people pissed off that you shoved an unrelated post into a tag they were looking through for relevant content. You also are going to be reported by people for spam. Because you are spamming.
