CSGO stressing a server.

Hello I've been using a stresser for a while now but for some reason I cant figure out how to stress a MM server. Ive stressed Faceit servers before with ease but with MM I cant. I believe its due to them hiding the IP. If so I could really use some help because Im tired of hackers. The reason I want to stress the whole server is because it would take a little bit of the game with a IP logger or wireshark to get the individual. If you could shed some light on the situation I would be so grateful!

Thanks,
