Did you know you can rebug a post that you didn’t author and tag it however you want and it won’t show up in a general tag search? You can add tags for filtering purposes for yourself on your own page or for other people to avoid things they don’t want to see and it won’t affect OP’s discoverability any more than a blank rebug! (However, if you add a reply to your share and use some of the same tags as OP, it will reappear in those tags.)
The only time new tags added to a post on a reply will make it show up in tag search is when OP does it themself.
