I think this so-called "Dormant Virus Effect" is a really interesting scenario and also none of our business.
In addition to that, I think it's completely unlikely. Managing the number of keys alone would be a nightmare. Making sure the accounts look legit would be a pointless time-suck.
Pointless because why would Steemit, Inc. care about having dragon's teeth on other chains?
@jesta had an interesting take on the fact that hidden stake accounts could deter airdrops and beneficial forks. Also ned has no issue with multiple keys, he had me help him broker a deal to purchase 20 accounts just last year. Didn’t even say thank you after, so rude lol.
Are you referring to a similar amount of accounts as a "dormant virus?"
