I actually made a few comments on their "100 day challenge" or whatever the posts was called. I think I made 3 of them in total. I basically just called Justin a liar & a thief, with the intentions of getting them to erase my history.
There is a tool one could use though, but I can't remember the name of it unfortunately. I never used it.
Edit:
I just looked it up.
The tool is called Steem Pruner.
You can read more about it here.
