What can I do if other players won't leave me alone?

In this case there are several possibilities which may help you depending on what happened. For example:

Contact - Contact the player and ask nicely why he is doing what he does and ask him to stop doing it.
Ally - Look for players who have the same problems as you and team up with them.
Gang - Join a already strong gang. A lot of gangs are open for new and weak players or have "wing gangs" for that purpose. They are also interested in helping you to get stronger and reach higher grades to secure your vote in the head boy election for themselves. Just try to apply for a spot in a strong gang for once.
Change of position - You can change your position inside the school building/the city using the "Setup" menu. If you just want to get away from particular players who are seated near you and don't leave you alone, this could already help.
Another City - You can take the bus to travel to another city and give it a new shot.
Without classroom - You don't necessarily need a seat in a classroom to play SchoolWars. If you were chased away once or changed your position just don't go looking for a new seat right away. You can still make money through the jobs and you can still skill your account which makes it possible to become stronger and look for a new seat in a classroom later.
Reset - If nothing helps you can also reset or delete your account and start completely new (maybe even with a new name?).
