Cyberdasm, from what I understand - the former image you provided is one of the regular uCoz advertisements,if its appearing on premium sites I can mention this to Sunny. As to the latter image, it looks like an index somewhere on the page has a bug, aside from that this again is part of the regular adds.
Sunny (or bigblog) will most likely have a definitive answer for you at a later date.
PS: I fixed the thread title for you.
