Not gonna name the site but know of a certain person who had a car seized as it was bought with proceeds of crime, funnily enough the same car was raffled by one of those sites not long after and a relative of the original owner just happened to win it!
All in all though most of those sites are legit with genuine winners from all over Ireland and UK. R Kings was making an absolute killing over lockdown, not sure if they are still as busy. Fair play to them!
