If you use Facebook, Twitter, or any other social networking site to promote your shop, please take this as a heads up---would hate it if any Etsians fell into this trap!
On Twitter, I got various messages saying:
"OMG, someone is complaining the product you just sold them."
"Look at these pics my friend posted of you. How embarrassing!"
(There were at least 10 different messages from 5 different users)
With the message there was a link. DO NOT CLICK THE LINK. It will spread viruses through your computer, and/or it's just a rip off spammer trying to get you to buy something. (my friend clicked---needless to say, it was a mess to clean up.)
Hope this helps some people out!
