It's almost like they're catching on to people stealing from them?

I'd try differing time lengths between each SE and figure out the time restrictions. If I had to guess, they might have setup a system which takes in data from refunds and logically determines if it's sketchy or not i.e. same address and multiple refunds in 24 hours, 48 hours, etc etc etc...

Use your head and don't be a skid. SE strengthen companies and when idiots use it, nobody is benefited.
