Delete Links

Hi, if the email gmail PVA is no longer working, how should i proceed to remove links ?

Is it still possible ?

Does anyone does this as a service ?

I would like to clean up all bad backlinks, is this better or should i just go for disavow ?

an email doesn't have to be valid anymore as long as you have the login/password fro the account where you have created a link. You will still be able to login and remove links with SER.

How can i check if i have the login / password for this ?

well if you have the project itself, it should have the login/password stored. Just links will not help here though.
