FR is my only Social Media, when it comes to other sites, I treat it like an untested Medical Procedure. Avoid it if possible, until more details are known.
I usually stay away from sites like that one, but it looked legit right up until the moment I put my “other” email into link.
Once I did it I knew it was a mistake. Now I am home and have been trying to get on to that email site (proton) and I am getting messages that there is an issue from my computer.
Lesson LEARNED!! (unfortunately too late)
