Hey Summoner,
Retaliation is almost never a reasonable reaction to other toxic players. The player you are retaliating against probably wants to see you get upset. When you get into an argument you are just creating new problems for the other players, and the trolls will just egg you on even more. The best thing to do is just mute them and report their behavior.
If you can't control your actions, I suggest muting them upon entering the match by typing "/mute all", or moving the chat window off the screen so you can't read it.
As for being mass reported, they have no extra effect on you. Punishment is calculated per match, not per report. False reports will also not hurt you, no matter how many people make them. https://ask.fm/RiotLyte/answers/133759089858

Riot also doesn't do infinitely stacking (permanent) chat restrictions anymore. The players that get them always used their limited chat to continue harassing people, or moved their abuse to griefing through gameplay. It simply wasn't effective for player reform. http://boards.na.leagueoflegends.com/en/f/cIfEodbz/d/45xUUKxk?comment=000400000001
Punishment also has 4 tiers, and are typically administered in order;
- 10 game chat restriction
- 25 game chat restriction
- 14 day account ban
- Permanent account ban
Except in extreme cases such as hate speech and death threats, you'll get them one at a time in order. It takes 3 months for your next punishment tier to drop down one step. http://boards.na.leagueoflegends.com/en/f/mNBeEEkI/d/p7scKW1K?comment=00050000000000000000
I suggest reading this material for more information on how you are expected to behave, and how reports work;

If you would like to contest your punishment with Riot, you may submit a Support Ticket, but Riot will not remove a punishment unless it was done in error.
Let me know if you have any questions.
