They may have done their own researches and they need opinions/suggestion from others especially from those who have real experiences on the site. Opinion of others is OK as long as it is valid, and OP is also free to decide whether he/she want to use other's opinions or not.
Seems like they aren't giving any priority to our opinions here. OP said that he will lower the rating of 1xbit because most of us has made complain about them. But he/she hasn't lowered the rating yet. Even the post isn't available now. Probably it was deleted by OP. Check the archive of
that post. Though I'm not sure, but I think OP has made paid review of some casino. He wouldn't give 5 star rating to every casino if he made those reviews by doing research.
