If they carry on do a screenshot of their messages and send to skimble to deal with.
If they still carry on after that...name and shame them. See how brave they are to do it in the open.
Skimble takes this kind of abuse seriously so don't ignore or wait for these idiots to stop.
Thats really sick, those are just idiots, look sis if the report didnt work out and if they still are bothering u, just give me any info about them if they posted any( email, accounts,....) and i will personaly hack thier phones, that will put a stop to it !!!
