Description
Quick summary
Approximately two weeks after publishing a single post on my new Wordpress blog, the list of tags contains multiple entries that I did not use in the post. I recognize some tags from the description of my own Mastodon accounts that follow the blog, but others are completely random (and some of them all kinds of racist/NSFW/...). The single post has not been interacted that much, so I'm not sure if all of them are from other fediverse accounts known to the plugin, or if there's some other mechanism at play here.
I feel that this should be considered a bug rather than intended behaviour, because it leads to a very polluted tag list. Also, it changes the resulting page when visiting, say, example.blog/tag/cannabis or example.blog/tag/some_racial_slur from the standard 404 page to a "nothing was found" search result page.
Steps to reproduce
Assuming that nothing is special about my WP/plugin installation, just visit the tags admin page at /wp-admin/edit-tags.php?taxonomy=post_tag and compare the tags listed there to your blog's actual content.
Plugin version is currently 4.7.1.
