Good morning everyone, in general I believe that online poker is reliable, but poker sites cannot keep the system 100% secure. Of course, there are players who are currently committing some type of cheating and who have not yet been discovered, but there are a very small number of players who do this, with very specific technical knowledge.
Any online system that involves money will not be 100% secure. Just look at the online banks that invest billions in security every year and even so, some people with above-average knowledge manage to circumvent these measures and steal money online.
In 2023, a player managed to find a flaw in the GG Poker software and had an advantage over other players.
On Friday (29), GGPoker released a statement clarifying the case of the player “MoneyTaker69”, who managed to obtain an illegal advantage by exploiting the room's software. The player was banned from the site's tables and had his winnings confiscated for reimbursement to those affected. Furthermore, GGPoker stated that the vulnerability that allowed the cheating has already been fixed.
But the chance of you playing against a player who is cheating is very small, on the most famous sites, sites that are not well-known the probability may be higher.
