I got 30 min timeout from Ranked because of striking dummies!?

Then let me help you by explaining how wintrading works.

The way wintrading works is one player makes sure to either play VERY badly or just not play at all when they play against the person they want to boost...

Not to railroad the conversation into the topic of wintrading but although this is very correct, this is also the very obvious way to wintrade (like that one player "Wemightwin Thistime" back in S1/2 who got banned) when players are attempting make a statement to the devs or to upset the playerbase intentionally and blatantly.

A more inclusive description of wintrading, however, is that it is typically done by players who are already very good at the game and can do subtle things during the game to throw the match without suspicion from the average player (allowing themselves to get CCed/making themselves an easy kill at certain critical points in the match). Which makes it very hard to police ALL wintrading, and which is why it will never end in any game.
