Hi, guys!
I don't really think the fact that you are interested in the "adult" items has anything to do with it. I have been having all kinds of similar problems, without ever having visited the "adult" section. The darn thing's just buggy right now!
I know eBay itself was down for me the other day - well, virtually down. All my items won/items watched, etc. showed as (0) items in every category, and when I tried to snipe, or even leave feedback through eBay, it said item not found.
Then, the next day, my AuctionSniper started acting weird, too. Perhaps the snafu at eBay triggered the problem at AS, or perhaps eBay made changes that AS hasn't caught up with yet.
You're right - it is intermittent, but more dysfunctional than not. I'm sure they're scrambling to fix it - at least, I like to think they are!
The sooner the better!
