I wouldn't recommend that. Since, to be honest, that makes you worse than them. Spreading toxicity isn't the way to go about it; do as both Digit and Lunestra said and keep screenshots of the incidents. If it continues then you can make a report for harassment. However, if you started to swear at them, they could easily report you for toxic behavior and I don't think you'd become immune to punishments because 'It makes you feel better' :P
