2] SUGGESTIONS:
A] CHANGE YOUR PASSWORD. Recent scammers have been able to access the account of longstanding members of websites across the Internet by hacking other databases/websites for login credentials. If a member is using the same username/password on multiple websites the scammers are able to utilize those credentials to login to ANY website where they are valid. They can run an Internet search for a username, and they are then able to login using that common password. Then, they impersonate a long-time member and try to make quick sales, OFTEN RESPONDING TO WTB ADS, or posting BELOW-MARKET PRICES on desireable items ... and demanding instant digital payment.
So ...
MAKE YOUR PASSWORD DIFFICULT: Use CAPITAL and lower case letters, numbers, AND SYMBOLS.
HAVE A UNIQUE, HIGHLY SECURE PASSWORD FOR EVERY WEBSITE! This is key.
B] VENMO, ZELLE, PAYPAL (especially F&F (friends and family)), and other instant payment methods offer NO or VERY LITTLE RECOURSE for buyers. Postal Money Orders are overrated and not much better. THINK TWICE before doing business with a seller who insists on one of these types of payments. Consider writing PERSONAL CHECKS or funding through a CREDIT CARD that offers you recourse as a buyer.
BUYER BEWARE!
