Mutedbanshee has posted a 'pleas read' image explaining what whe knows in the gallery. I've posted a note in the galleries as well as the removal of past entries seems to be going beyond the call.

Also took a look at the TOS. There is no explicit mention of conflicting areas, (I.e., contest in galleries and in the contest area). Just the one liner mentioned by Blazerwiccan above. Seems like an interpretation question as the TOS does not provide enough information to determine that a contest is only allowed in the contest area. (Perhaps it is implied, but you don't go rooting out everything on an implication.) Also, the contest area has no statement that it is the only location for contests.

I also went through and changed names on the images I had left from past contests:-(
