yeah I think that is 1xbet and not 1xbit though there are threads and accusations here about them having connection or even owned by same person/team but that is different story , because like you i have not seen any social media influencer that advertising nor promoting this scam site , actually 1xbet is not facing any scam accusation here directly to their name(at least as far as i see) instead they are being called as same owner as this 1xbit scam , but in other area there are several issues that i have read that ixbet is also scam.
There are many, many scam accusations against 1xbet which is why it's just as shady as 1xbit or maybe even more. Personally, I tend to avoid gambling sites starting with 1x these days.
1xbet doesn't openly scam customers like 1xbit, but they cleverly scam them here and there using their sponsorship deals etc as their shields.
There are definitely alot like you said, but for me personally, I have gambled On 1xbet on several occasions, I mostly played sports betting on that casinos for several months, and needless say that, I never had any issues, both in terms of them crediting my winnings and me withdrawing them, never had any issue, and one other good thing I will also have say about 1xbit is that, they sure have a sports book with one the best odds, and one feature I like in that casino which I unfortunately have not found on any casino (even on my favorite casino, which is stake) is the ability to still win a multi bet ticket even when one or two games from the ticket fail to meet up as predicted, 1xbet have a system that minuses those failed bets in the multi-bet ticket and only pays the gambler for the games that was predicted correctly, only that they pay at an odd that is lower than what it initially was - this feature I've found to be really helpful for gamblers since it has helped me win some of my multi-bet tickets which should i ordinarily should have lost because not all the games in the ticket played as I predicted.
So, that is it for the good side of 1xbet, now coming back to scam accusation against them, I would first say that, there is actually no online gambling casino without unsatisfied customers, and personally, I've always thought or assumed the majority of scam accusations against 1xbet is possibly due to their connections with 1xbit, which is a well known scam casino themself.
