I hadn't checked my logs for awhile. I checked a few days ago. The same buyer had hit all 3 accounts. My larger account she hit each item 3 times before moving on. She'd tried to bid on (I think) 26 different items. I would have given up after the first few.

Then she moved onto the other accounts. The second account was also tried 3 times per item. She tried to bid on 9 different items. The new account she tried 4 different items.

I kind of got a bit of satisfaction seeing her hit on 3 different accounts. Mught make her realise there are consequences for not paying.
