True. Some of those trolls are actually employed by rival casinos which is why valid proof as you mentioned helps a lot.
It's the case with most of casinos where reputable and legit casinos are targeted by spammers without any valid evidence and just trying to defame them so people start arguing about it and raising concerns but that doesn't helps a mot because the players who are gambling regularly with casinos like Roobet know they won't scam them with few hundred or thousands bucks unless players have violated any of the casino terms or trying to cheat them.So trolls should be ignored without giving much attention to them which they desperately need.
While I agree, all cases need to be researched by the team as you will always have some legitimate cases. Costumer service is service underrated but so important for any company. I just checked trustpilot and to my surprise, they score extremely high over there: 4.7/5. Never seen a casino so high as most of the times, you will have more complaints than positive reviews on there.
Those legitimate issues will be solved by providing validate evidence along with those claims and it happens many times and casinos let them withdraw the amounts after the matter is resolved.Sometimes it's just a suspicious activity from a account that led to this issue but it is resolved apart from those all just trolls and spammers trying to cover their loss with cheap tricks.
Sadly enough, you will always have a lot of trolls and spammers. But I haven't seen a lot of cases against Roobet in the last couple of years, meaning not a lot of people have had an issue with them. I don't really play anymore on them, but never had an issue and all my withdrawals were quickly processed also.
Easy to spot a trolll and usually they are the one posting an allegation without any valid proof presented so they should not taken seriously since people will just waste their time and effort to look at those issues they want to rise up. And also Roobet is really a good platform that's why those trolls maybe they realize that any attempts will not work to them that's why those people go to different casino since those are easy target for them.
So far we can't see any serious issue posted against them and that's good for us gamblers since that determines how really good they are since even their competitor cannot throw some shade so we can say for now that their existing players play in a good casino.
