Huh.
You can see some original comments from that date.
However, trying to view them takes you to a url like
https://abit/test#@abit/re-abit-test-20170719t102724533z
and
https://abit/test#@abit/re-test-re-test-half-1
which is of course not accessible.
However if you go to
https://steemd.com/tag/@abit/re-abit-test-20170719t102724533z
You can see more info.
Might this have something to do with the fact that it's has null tag?
And if you watch carefully, he got some comments with 1$ payout. Who knows if there are more of this type but with hundreds of sbd/steem?. I tried the null tag before and didn't do the same thing.
