We've got a few malicious folk setting up dummy accounts to buy large quantities from Etsy sellers tonight.
If it happens to you, don't worry -- just drop me a conversation and I'll take care of them and clear out everything they've done.
It's a lot of work for them to do something that takes us very little time to fix. ;P
