Question about account sales, identical emails

Created a botfarm not so long ago and wasn't very creative with the emails I used, I'm also looking to sell these accounts but was wondering if it'll impact sales, would rather be upfront about everything then have complaints later down the line,

so my issue is I created some pretty generic emails, for example

- [email protected]1
- [email protected]2
- [email protected]3

(None of these accounts are email registered)

Emails are all identical apart from the ever increasing number on the end, I'd have to change the password to each account upon sale so at least that would be unique but 1st password created with the account wouldn't be able to be given out...

Are these accounts useless for sale because of this? Cheers
