Well, I am just a lowly volunteer moderator (who should be accorded the title “Big Kahuna” 
) and I do not have powers to give or take signatures or titles.
My assumption is that your signature disappeared because you kept spamming other people’s threads. Somehow you still don’t understand that, and I doubt your signature will return until you do.
And still you are complaining and asking for apologies (for what?) instead of being a useful member.
