This has been answered from a post from 8 years ago so I'm not sure if that's still accurate and asking again..
I have a few ebay accounts and the emails/questions are all forwarded to my main/real gmail (banned). I got an email from a buyer today, which was forwarded to my main gmail (banned), and accidentally responded instead of logging onto that gmail/ebay account and responding directly. It got rejected by Ebay. I got an email saying my communication was blocked bc my main gmail (banned) was not registered to that ebay account. This is the message I got automatically:
Your message to USER ACCOUNT was blocked, because it wasn't sent from your registered email address.
Will I be linked? Or not going to be a problem? I have a few listings up. Not sure if I should just end everything and let it cool off for a week or two before listing again (or that'll be even sketchier).
The complete step-by-step guide to get back to selling today!
ANOTHER Ebay bot could come along ,link the 2 email accounts and suspend you,who knows,time will tell
removin the listings wont save you,if you want a quick sale,then lower the price and give them away
