How to make people lose connection?

Hi guys! Sorry for not introducing myself first but i am so interested that i must ask straight away.
I play Total War games for a long time and since the release of Shogun 2 a lot of highly ranked people use tools to make you drop out of the game and "loose connection". I have never used hacks in games but i am just so eager to see how that stuff works and want to try it. So i need help around it and will really appreciate it.

Edit: I have post it to wrong section. It should probably be in a Hack Requests forum

Anyone? If you don't know what i wanted to tell (English is not my native language).
For eg. : I found a 1v1 match, game starts and when my opponent start to lose he kick me from the game somehow and i got notification that i lost connection but actually i was "drophacked"

Hmm... Can't believe that no one even try to answer.

So you want people to disconnect?

Yes. Correct!

Well, in most of the games I've played, people disconnect others by spamming.

Spamming what? Units? LOL
Help me please.

spamming... as in chat attack?
If you were talking about making others on your network disconnect i would suggest a program for that. but since you aren't. i can't really help there. other than saying perhaps reporting them as bots if the game has that option. then they could be booted if they dont do what they have to, to stay online.

Oh! Finally... Sorry for a late reply. I am talking about programs that will enable me to drop my opponent from the game. It is a P2P game and i have noticed a lot of high ranked players are using such programs.
