wow good find.
its not the communtiys problem.its going to be a huge problem for steemit.
goverments may seize steemit when the first account does something bad.
its all about know your customer now.if they don't bring in a know your customer verify check say every 3 months,it could come back to bite them in the ass.if they show they been banning sold accounts and seizing the steem on them.may be donating it to a good cause.should cover steemit.
I wouldn't touch them. should be easy to have checks in place.then boom you lost all that money you just spent on buying that account.no different to banning game account that are sold.
