This has been going on since…. probably since schools were first invented.
The recommended method if you’re being targetted generally goes along the lines of:
1) Tell a parent or teacher in good detail what’s been happening (this is the modern day recommended method by 1960’s/1970’s hippies who grew-up and got jobs as teachers…. it doesn’t usually work, but at least covers your ass if you have to resort to stage3).
2) If parent or teacher actually does something about it, bullies tend to keep a low profile for a few weeks before kicking off again because you told on them, in which case resort to…..
3) Beat the crap out of the bully, or find a few bigger kids to do the honours, then they usually finally start getting the message it isn’t a good idea to screw with you, and leave you alone. (this is the time honoured method recommended by the poor long suffering parents of the 1960’s/1970’s hippies, and actually works)
