I made a FB account to change a client's Page settings, and now I pretty regularly get emails from FB along the lines of "Having trouble signing into your account?" because there's been tons of failed repeated logins. I think it might just be a normal part of having a FB account? Can't speak for the other services.

That doesn't sound normal to me. You should tell your client that someone might be trying to hack them.
