Some referral systems that I know, the referer does not take responsibility of the outcome. It is stated that the work of the referee is to bring people to patronise the business. Although it is expected that before one could refer others, they should first trust the system and believe in it. But it doesn't mean they should take responsibility if anything goes wrong. Unless the referer is in partnership with the company.
but what I mean by being responsible is that at least the team or owner of the casino review site really researches the casino site that you want to include on the review site. thereby keeping the customers away from the rogue casinos that are on those review sites.
for example, like BTCGOSU before entering a casino site on its review site, the BTCGOSU owner will thoroughly research to get real information about the casino and be declared worthy of being added to his review site.
and if one day one of the casinos added to the review site becomes a fraud, at least the owner of the review site must immediately blacklist the casino so that there are no more victims.
