A quick note: I'm aware of SE's position on this, which is that this isn't an issue since "nothing can truly be erased from the Internet". I'm holding off on posting a self-answer because I want to see if someone else can phrase it better, and provide a community stance on this. I'm posting this because someone has ranted about this on the main site I participate on. Also, this question isn't necessarily about me; I'm following advice here that this should be a separate post.
I've posted a number of comments on this site. I noticed that some of them are posted in chat as a result of the IPS Comment Bot since they tripped some regexes to try and catch chatty comments.
Later on, I searched for my username on chat. I noticed that just about every comment I've posted both on the main site and on the meta site has been oneboxed in the bot's testing room, regardless of whether it tripped a regex or not.
On most sites, I can post a comment, and it wouldn't really be searchable, and I could delete it at any time. However, my comments on this site are pretty much permanent and searchable; if a comment has been deleted, someone else can link the words back to me by searching in chat. On other sites, this isn't possible unless a moderator manually moves comments in chat.
Is this a problem? What should be done about it?
What if I want one of my comments oneboxed in chat to be deleted? Are such requests accepted, and if so, how do I file one?
