Once they get your email they fill it with all kinds of junk. That's why some people set up a 'Throw Away' email on their Yahoo and possibly other email accounts to catch the nonsense. I have 3 emails: Yahoo for everything, Proton for emails that require security and GMX which is also secure.
I know. I'm an eBay seller myself. I like to try and give forum pals a chance to sell/buy with myself before They or I go to eBay. eBay charges 12% of the selling price to the seller and with shipping, it can be ridicules. I belong to 3 other forums also. ChallengerZForum, vMaxForum and V4MuscleBike.comForum. I like to sell and buy from member friends and also enjoy communicating with people all over the country that have the same likes as myself. It's fun and I've met some very nice people. I guess it's an Ole' Guy thing.
