this is not the kopitiam, i believe i've warned you before. We will answer your queries after we conclude our checks, in the meantime, please don't come up with your own conclusions.

your avatar was not removed, if it was, it will be replaced with a "no-avatar-selected" image. The link to your avatar somehow is deleted/corrupted. It is most probably due to either you trying to upload a new avatar which didn't complete, or a problem with the link to your avatar.
