Really? Till' this day I had thought that Truspillow was quite a trustworthy review site

I mean, they display quite a bad average review summary for 1xbet
And they seem to be aware of the shilling campaign when comes to 1xbit
Trustpilot is trustworthy sometimes, but untrustworthy some other times since they aren't always transparent. They usually end up doing under the table deals with certain shady sites in a mutually beneficial manner.
If they were 100% legit, 1xbit's ratings would most probably be lower than 1xbet's ratings due to the negativity surrounding them.
