I've been following this thread for a little while, and it really does seem like most complaints are related to live table tennis bets.
1xbit had 2 choices how to deal with these issues, and they were:
1. Remove live table tennis betting so that they can fix their reputation
or
2. Keep the live table tennis and just take the money of any of the people who try to abuse the market inefficiencies
They seem to have taken the latter option, possibly because their reputation is already at an all time low.
With regards to this, are there actually many people complaining about 1xbit in other events apart from live table tennis?
