Someone made a fake teachers twitter should I report it to school?

[owlpal]

there is a teacher at my school who i think is lovely but he gets teased alot by a certain group of boys, this time they have gone to far and have made up a fake twitter pretending to be him and are posting abusive messages from it about his apperance and family, I have a very strong idea of who it is. my question is should I report it to my from tutor and ask to be anon? I feel really bad for the teacher as he has enough stick already and hes truley nice
Im in the last year of secondary school (year 11) I really feel like I should say something but i dont want to say the wrong things

That's horrible, they could get done for identity fraud. It's hard because if you tell the boys to remove the account and they dont you cant tell the teacher because they will know it was you. The best thing to do is to ask him about "homework" after class on day and the whip out your phone and be like "Sir, i dont want to really tell you this but someone is pretending to be you. But please, i dont want anyone to know it was me that told you"

i say you should and do tell him not to say your name to anything. but that's just me you can do what you want, just know one thing telling your teacher will be the right thing to do.

That awful! You should report immediately. I don't think you will say the wrong thing

If you're afraid you probably should stay anon. but know that you're doing the right thing and hopefully there's nothing to fear of
