Due diligence needs to be taken whenever anyone is considering tagging anyone.
I agree and looking at it with a different angle, the tagging part isn't the only issue (they can also get kicked out of the campaign or get nothing in return [apparently, "
a manager did that"]).
For example, post history is normally a good indicator. People are their own downfalls to habits. We all have habits, and unique styles of writing.
There's also the possibility of doing time analysis to identify whether the alleged connected accounts timing links up together. It's not really same address = connected.
I agree with those as well but still not sure if it can apply to all of the cases (haters/scammers are getting creative [unfortunately]).
For example you have joined bounty with and eth address/Twitter/FB id. Then I am your hater, I like to tag you and I joined using your eth address/Twitter/FB id. It does not mean we are connected account. Both account basically will be disqualify from bounty. Specially it will happen by new account. Even I am your hater I will not use my ranked account. In these case no one will tag. But if same eth address/Twitter/FB id using by multiple bounty and continue campaign, got stake then it will consider connected account.
That's another issue that I just explained while responding to "Welsh".
This can happen and the only way to stop people from abusing bounties like this is that they need to post "Proof of authentication" - that they own that account and are not trying to impersonate them.
Unfortunately, that only solves the issue if the impersonator was going to use the same account/forum name (how about other methods [Twitter & FB ID/address]?).
Still I have not seen such cases but would like to know how DT would handle them.
Likewise...
A bit similar to what I was looking for but that one had a solution (regardless of that, thank you for posting it [I used a response from its continuation thread, as a source for the above example]).
