"Photographic evidence" has recently been posted on social media, in particular by someone who is just lately only an occasional contributor on here, that one of the major high street bookmakers is using quite a sophisticated piece of software to analyse the handwriting on betting slips submitted in the shops in order to identify succesful punters and no doubt stop them or at least limit their stakes. I have used the plural version of bookmaker in the thread title as no doubt if one of them is at it, then so are others.
Not a bettor so don't know if this is necessarily something new, but is there nothing bookmakers won't stop at ? Anyone else had reason to suspect this ?
