Ex creating vindictive messages.

[ConsumerUnitNotTraceable]

My ex partner has started to create some really vindictive, fake messages about myself and my family (composing them as if they were from me and then taking pictures of them)

I've obviously got zero proof they're not from me, apart from my word.
He has now gone around sending them to various members of our friendship group and the stuff in them is blatant lies.

To be completely honest, I don't really care. I have much bigger things to be worrying about than some twat being just that; but I am slightly concerned about the implications should these messages get back to my close friends/family members (whose 'secrets' lies are contained in these messages.)

I've had a few texts from the friendship group asking about them and I've said 'Look, they're not from me but if you choose to believe otherwise then that's up to you. You know me well enough to make up your own minds.'
Most of them agree that he's composed the messages and sent them to himself or something similar.

AIBU just to let people make their own minds up on this front? There is really nothing else I can do and getting massively bent out of shape will look as though I've got something to hide I suppose?
I've honestly got so much on my plate right now that it really doesn't concern me in the slightest (close family death, terminally ill friend, MH issues...)

You are doing exactly what you should be by ignoring this twat. However, if he continues and/or the messages get more extreme and possibly damaging, you might need to report him to the police. This is clearly harassment. I would ask one of the trusted people who is getting these messages to send all of them to you so you have a record.

Misuse of Telecommunications Act. He can be charged. It is, as mentioned, harassment and it only takes 2 counts to be convicted. Phone the non-emergency lone. He’s slandering you, 8n effect. Hard to prove, slander, but the Misuse of Telecommunications is easier.

Thank you for your replies.

If he continues being a twat I will report him to the police.
Right now, it's silly, vindictive, playground type stuff.
Not really hurting anyone but not ideal either; as I say he can make up what he wants about me (after what I've been through recently I really couldn't care less what people think or say about me thank god for diazepam) but bringing family and friends into it is a little more vexing.

I didn't realise it could be reported as a crime so thank you for the links.
