My ROBLOX account was hacked MULTIPLE times throughout my experience with them. The first time or two a few years back were my fault, I was a child and didn't know anything about security.
The most recent ones, however, were not. I had secure passwords that weren't used on other sites, and it was still hacked. My account was Lifetime OBC and also had a fair amount of Robux. I verified it with my new email, as I lost my old one I had as a child, after a *** a few months back.
At that time I also used my Phone Number to verify. The hacker was allowed to change my email, verify it, remove my phone number and everything; all without my receiving a single email about any of it. There has been money spent on the account, thus I am extremely pissed.
Support is pretty much saying a big *** you.
