Mailnesia vs Gmail and others

Previously when i used GSA Search Engine Ranker i used to input my manually created gmail accounts, but i would get an alert from Google saying "Someone recently tried to use an application to sign in to your Google Account" Because i was using multiple proxies and it looked like someone was trying to access my account from another part of the world.

But now that GSA and other programs like Licorne have the ability to quickly and easily create dozens of Mailnesia accounts, is there any point in me creating or buying Gmail or Hotmail accounts?

Are they better then Mailnesia?

Mailnesia is pretty amazing. I have to fend off hundreds of accounts that have used Mailnesia, that are attempting to spam my site.

so i should just give up creating Gmail and Hotmail accounts and just use the Mailnesia accounts that the program creates?

I've also noticed that with GSA i get a lot more Errors trying to check Mailnesia files
