There are taggers on Safebooru that go to a post and remove every single tags just to add a ambiguous tag (such as random numbers) and add some weird tags that aren't associated to the image (like cuntboy),this is bad,because what if the uploader has a Hard work to add the tags?
So for the taggers who does these,please stop

that's a problem for sure

Yeah that's a problem,even worse is that when we give the tags back,when we go to the post,the tags are removed again and the ambiguous tag is back

This is usually not something that Moderation can detect, we rely on other users to report it or even just seeing it ourselves to know it is happening. If you see it happening, just send a message to a moderator and we will take care of it, we have tools to prevent further abuse. I am currently aware of some of the images where this is happening.

and don't forget the taggers who put absolute gibberish in here
