Inactives

Someone for reasons unbeknownst to me recently botted me 5000 followers on ig making my already pretty shitty engagement rate even worse. Would really appreciate it if someone could tell me if there is anyway to get rid of all my ghost followers? thanks in advanced

Block them one by one. I guess you can record a macro or something, so you don't have to do it manually. I don't really know any other way.
Or be patient, wait for the next ig purge and pray that those accs will be among the purged ones.
