Personally, this does look suspicious to me. However, one has to provide proof if making allegations, that is the way it works. Innocent until proven guilty. I think both sides must now provide verifiable proof of betting history. It doesn't look good if things are altered.

Maybe if one or two bookmakers can make an enquiry into the league and check, and see if other suspicious behaviour is replicated on other platforms?

While user has not offered any explanation for this betting history, he says he will explain the strategy. If user is from Finland or Brazil it makes sense but seems user is not?
