Owl.games was indeed a very trusted casino, infact, this casinos was like either the first or second casino I began my gambling journey from, I played on owl for several months, if not up to a year before withdrawing every fund I left there and decided on trying out other casinos as I felt I wasn't lucky enough on their casino.
Though owl recently have started misbehaving, I think its too early to start to compare them to 1xbit, 1xbit is a known scam casino, owl might just be going through some hard times at the moment, and whether they decided to leave this forum because they are no longer happy with the forum, thats absolutely up to them, and i still would advice gambler to avoid them for the time being.
You don't look like a noob and then there are so many great casinos that have come up before them but most of them are centralized while this Owl.games was one of the early casino who introduced web3. Maybe this has caught your attention? Your decision of leaving them might be right. The constant losses that you felt might be a sign or a start that their casino is now starting to go bad.
Eventually, there are lots of complaints coming up from them and they lock their thread. I think that is to avoid the complainants. If Owl.games is not guilty, they better reply about these complaints that they are getting in order to clear their name.
