Ebay cracking down on listings?

I don't know if I'm just unlucky or ebay is cracking down on "set builder" listings. I have been selling "you-pick-5" lots of Topps Heritage SP's for years now and never had a problem. Now in the last two weeks I've had 6 different listings cancelled. Anyone else notice this? I've tried different wording and keeping it vague, but I'm still getting nabbed. I see others selling these kind of lots all the time.

You either had an angry buyer (probably not with the new cards you sell), or more likely, and angry competitor.
Most of the time it is a competitor reporting you.

I must now be on ebay's radar screen. I've tried re-running auctions a few times in the last couple of weeks and they have been relentless in shutting them down within a day or two of posting. I'll chill out for a few weeks (its a really slow time now anyhow) and see what happens in the fall.
