I had an item I listed May 25th get a Buy it Now Bandit on the 2nd who within 10 minutes wanted to cancel.
It had gotten to maybe 20 hits in that time and picked up a watcher.
I relisted it at the same time I ran the cancel through and the interesting part is it now has more views than it did in the 10 days or so prior.
It's the only one on eBay, a car part for a specific set of model years.
Maybe this turkey did me a favor, although it would be nice for it to not cost 30 cents too.
