I feel unfairly blocked as it wasnt actually me

Ive been blocked. I am now unable to admin the groups i run so users cant get approved inconveniencing them. The person who misused my computer will never be allowed in our home again and i have now put a password on the lock screen ... I left my computer for * minutes to urgently go to the toilet and while i was gone a guest who i have now thrown out of our house decided it would fun to make inappropriate comments on my profile which was open i did not make the comments. I admin a number of groups and being blocked means i am unable to approve new members or answer member questions. The cause of the problem has been removed and i feel i should have the block removed.*I am not even able to remove scammers from my groups allowing fraud to carry on unabated

Dozens of people wanting to join my groups are also inconvenienced and existing members are unable to communicate with me

I would like to be unblocked i will ensure no one else will use my pc again

I was banned for one day and since then i have been careful about what i post i would not have made the post my former friend made

Nothin else i can do i have ensured there will not be a similar incident**Still waitin on a reply i have over *** enquiries to respond to and members are being inconvenienced
