I tried online gambling in the middle of last year, got a few decent wins meaning a >£2000 balance which instantly means you have to send your life story just to cash it out, a few days later ‘yeah we’ve decided you can’t lose more than £800 a month’
After that I just sacked it off and signed up to Gamstop for 5 years
