Msp and siblings don't mix

Hi. Sorry but this is just getting very annoying. If you are going to leave your msp to go and do something please log off your account. People keep sending me messages. Sometimes really horrible. Not long ago someone randomly messaged me and called be a bully even though I hadn't done anything. Then like the next day after I said I was blocking and reporting them they said it was their sister. This really annoys me as sometimes they are telling the truth and sometimes they can be lying. This really annoys me. Take this msp and siblings don't mix! I hate the mean messages I get and then as soon as I mention the word report/block people always say it was their brother or sister. If this continues to happen I will block straight away.

Here is a picture of the messages someone sent that I was talking about before.
