All books may be doing selective scams. I don't want to shill for 1xbit but are there complaints in the last two years? The ones above are 2021 or above. I'm not going to play there since it's not worth the chance but all these complaints are old.
The examples quoted above are just examples of positively resolved complaints.
There have been complaints over the past two years, but most of them were reports with no evidence, or someone posted the same story dozens of times over the several months, which gave the impression that there were many more complaints than real number.
