In all seriousness - not sure about the UK but here in the US Department of Labor has laws regarding internet at the work place and social media accounts and use. I know if the employer does not have you sign an acknowledgement regarding either - it can't be held against you. Maybe something worth looking in to? Unless you recall signing a document at the time of hire covering these specific things being prohibited?
That truly sucks man. Good thing you are working again, tho. Wishing you all the best, dude.
