Is it allowed to have a seller account and also a buyers account? Two different and separate accounts.
You’re not allowed to have more than one account. If you have more than one account, all of your accounts can (and will) get banned.
Yes catwriter is absolutely right.
Every person that has an account can both buy and sell, so you do not need two accounts.
Very correct. But Reviews are not visible on a Buyer Buyer account. If you know what I mean.
