I have spoken to him about it and he is going to do a little bit more homework on the issue - by bad payer I meant non-payer. Surely if someone procures a service from you and then doesn't pay they have no grounds to stand on?
When I referring to 'bad payers' for landlords I did actually mean people who had done a runner without paying rent.
Its a tricky one for sure,
The first thing that springs to mind is they are going to say they had a justifiable reason for not paying and you have made libelous or malicous statements and made them public (on the internet site) and they will sue for defamation and/or libel.
The next thing that springs to mind is the Data Protection Registrar will want to see a copy of your licence to hold data (which if you have your customers names and addreses stored on paper, disc, computer or any other format) you should be registered already!! He will then want to know how and why that data was made public....remember that fiasco of the lost discs a few months back
Losing/selling/releasing data attracts heavy fines.
The next problem is going to be evidence - If you havent taken this person to a small claims court and been issued with a judgement in your favour then you have no evidence (in law) that what you are saying is true....thats why we have county court judgements, a judge/magistrate has listened to all the evidence and issued a judgement.
Indeed, it could be argued that all of this is adequately provided for with Equifax and other credit reference agencies and what you are doing is unlawful and malicious.
Be very very careful.
