Is bullying at Uni common? I hadn't thought so... yet two very vindictive people are following me around, sending abusive messages on facebook and to my phone all because of....???? No idea...If I had to guess, I'd say it's because an agent approached me... I suppose, does anyone else have this problem? You achieve something, or win an award with writing and suddenly you are being mobbed?
Stand up to bullies. Confront them and ask them why are they doing it. Most won't be able to answer you, and tell them that if it continues that you will approach the authorities.
I am at school and No , I haven't faced this problem though I have won many awards.
I would say just go and report them!
Do what Damien says and if they doesn't stop, go to a tutor or someone you can report them too
