I used to be a toxic player, however I am trying to change my attitude towards others at the moment, and be just a better summoner in general.

My only question is, say ive been reported 25 times, and then I go into the tribunal with 5 different game cases, and they decide to ban me. Are the other 20 reports just thrown away and I get a second chance to redeem myself, or will I likely be seeing myself in the tribunal soon (as in the reports carry over).

after your punishment is served they are stored with that punishment and arn't counted if you continue with being disruptive. However, if you continually get reported and banned they will have an impact for the decission to being perma banned.

So i guess to answer your question, no they don't count for your next ban, but they will make a difference if it comes down to a perma ban.

If im good for X amount of time, is the next time reduced, or no?
