99.9% of the time I've noticed that it's usually 
right after another "big name" site updates 
similar cels or cels from whatever series you 
were selling. The person who offered to buy the 
individual sellers cels usually wants both (and 
impulse buys) and then figures it's easier to 
ditch the individual seller than a big name 
seller (like Anime Taro) because the big name 
seller is more likely to ban them (meaning the 
loss of a huge amount of cels because the dealer 
constantly has new stock) if they don't pay. 
Screwing the individual dealer over only means 
that they are going to be banned from buying 10-
20 cels instead of 1000-2000 cels.

I've also had things happen where the parents 
found out that the kid was spending his college 
tuition money on cels, or someone ran up their 
credit card, or they can't make their house 
payment, or whatever -_-#
