Posting gibberish for the sake of it, is insulting to everyone and the site. Seems a few think this is ok for some reason and its not so for those that do it stop now. For those that continue they will be warned and then banned from the site. Not something we want to do and hopefully wont have to.
If you dont want to post a Thank You or something relevant to the thread you could contribute to the site by posting Not much to ask really.
