Just started the process of editing all of my Reddit comments
they will probably just rollback all your comments, like they did already for a bunch of people. though at least that could cause them to have a problem with GDPR and similar data protection acts.
Though I think if you want to salt the earth you could instead bloat up every comment to max comment length, preferably with a funny story about data protection created in chatgpt. This might increase the server space needed for each comment. Maybe even add some disclaimers and stuff that this comment is your intellectual property and editing it without your knowledge and approval makes the site liable to a fine. This probably doesn't stick up in court, but whatever, maybe some employee will still think twice before changing back your comments.
