I have a couple questions:
1. Were the cards marked delivered by USPS?
2. Was the comc account charged for the cards?
3. Is the eBay account noted for selling the cards correct?
If the cards were marked delivered and the account was not charged, then I could see USPS theft. If they were charged as was reported on twitter, then I would have to assume comc theft.
If the eBay ID reported as selling the cards is correct, then I am very concerned since that account has existed since 2007, but did not start selling until november 2011 and has been posting in (what appears to me to be) batches. The pattern is disturbing.
For the record, I will still be sending cards to comc.
