I see trolls always getting the spike first and I don’t understand how; does it have something to do with the pc specs and fps/ping or something?

Also I heard you can take the kick the trolling defused by pressing defuse but it never works for me. I’m not sure what the “press f to kick them off then defuse” means either: I heard it was just a hint to hold defuse, but I also heard it is an actual mechanic, and riot refused to release official notes on it. Honestly at times it seems like riot is intentionally helping the trolls.
