I am sure that @xpilar's reputation is so strong that nothing really will ever destroy it @stef1 he had done many good things in the steem platform to support many users until now so I guess that these issues against him will just be ignored by members of the steem community.👍
I know what you mean but as you also know people will remember bad things and forget good very quickly. They will definitely remember such accusation like: liar, scammer and racist and this is the worst thing.
