What does this mean?
It mean you are dumb for clicking obvious scam.
This is harmless. So you are safe... for now...
How do I prevent this again?
Don't trust strangers who send you a link, even it's not free money or some shit.
Free Robux, Vbucks, Valorant Points, Skins? Don't trust them.
This is harmless. Some scam websites can have a malware such as steal your IP, steal your accounts etc.
