You won't find theymos all over town because he's a very busy guy and he's very less active on this forum. Welsh & mprep and examplens already suggest you that.

However, one thing is that there are several third-party tools for this forum that have a backup of every post in this forum in the database. For example: ninjastic.space,  talksearch etc. you can message their owners and they will review your request and delete them from the database. this is the only way to permanently clean your post.
