[SKIP TO THE BOTTOM] IF YOU CBA TO READ THIS:
Are you familiar with DDOS? In MW2, it is said that DDOS is when you kick someone and they lag out - This is not DDOS/a DoS attack

"In computing, a denial-of-service (DoS) attack is an attempt to make a machine or network resource unavailable to its intended users, such as to temporarily or indefinitely interrupt or suspend services of a host connected to the Internet".

Why am I telling you this? This morning there was a hacker in my lobby, I told him I was going to kick him, he then threatened to DDoS me, (obviously I didn't take this seriously lmao), after I kicked him, he did it - I lost internet completely...

Had to get someone to call our internet provider to help me

[LONG STORY SHORT]:
Basically, if someone DoS attacks you, let me know

P.S.
It's really helpful to have steam APP on your phone, so if anything goes wrong (doesn't have to be something as extreme as this), you can still login from your phone and get help or whatever
