If I set up a dummy Gmail address and provided it publicly on Twitter, how difficult would it be for your casual meathead to tie that to my Linkedin profile?

I'm not talking about protecting against 4Chan or anon hackers, never cross swords with weaponized autism, but what is the doxxing risk from average Twitter bozos for setting up a dummy gmail and providing that publicly?

Basically zero chance if it's truly anonymous/isolated,newly created with no history, and you don't do anything careless with it. I presume the Twitter account itself is being treated the same way, i.e being created with this gmail account and isn't pre-existing.

I like Proton's "Simple Login" to create aliases.

For example, feel free to send e-mail to me at proton.ezqw0@8shield.net. One spam and I just shut it down permanently and will never get another e-mail to it. It completely hides the real e-mail address from he sender.

You can even set it up to protect gmail addresses.
