However, a lot of people are doing this, hiding behind alt when exposing someone's alt (when they are high ranked). Because they fear to get neg tagged or maybe they don't want to make enemies.
I've also exposed some high ranking users instead of newbie. Some of them have been proven guilty and legally tag. There's no reason to be afraid and hide behind alt if what you're trying to convey is true, even if proven guilty users are against the tag then I'm sure they won't have the power to stand against you.
It takes courage and enough reason to tag and accuse someone, if we are wrong then this will damage the reputation of other users. In the real world the police won't jail you for no reason and they won't make arbitrary accusations without being backed up by solid evidence, so they have to understand that the system works for the wrong things.
I'm not trying to say that you shouldn't expose scammers and cheaters at all, but there's a right way and a wrong way to go about it. It's easy to accuse, of course, just posting something without valid and credible evidence. I doubt that much harm would be done by such an accusation, if it's not impartial, fair and correct then people are going to see right through it. But if you present things correctly then people will more likely accept your argument for what it's worth instead of dismissing it as biased. Regardless of whether you use your main account or your alt account for it.
If you feel the need to expose someone, at least make sure that you have valid evidence and they're actually guilty of doing something wrong first!
Would you mind explaining what connection you have with FanEagle and Captain Corporate? According to the blockchain, You have made some transactions with them. Based on that, I suspect something.
Don't you feel awkward on asking me where and why I spend my bitcoins? You are not my government legal/tax entity to ask such questions.
But he didn't ask you where and why you spend your bitcoins. If you are not comfortable answering such questions, you don't have to. No one has the right to force you to do it, but then don't complain when someone else validates their suspicion by the blockchain evidence linking your accounts together and leaves a neutral tag on your account based on that.
