Could you please tell me who @ety001 is?

He's a developer from the Steemit team. Pretty much every developer on this platform who runs their witness nodes would know ety001. Any issues with TRX rewards, spam accounts on steem, and the whole steemit.com is partly maintained by him. So, the platform that you and I use regularly is all maintained by him and a few others.

there has been never any real proof that @steem-supporter did use his position to hack any accounts.

I was one of the people who was affected. In fact, the whole of bestofindia community was affected by this. I have said this several times before as well, I cannot trust this person until he gives me a solid claim that I can believe. I have told this to xpilar as well. I do believe xpilar is doing right but steem-supporter has not provided any evidence of why people should even be trusting him.

@crypto.piotr here's a trip back down memory lane where your account too was abused. Probably never noticed. https://steemit.com/xrp/@cubexagon/xrp-is-it-the-future
