A medical doctor is not going to try and remove you from life intentionally. There are measures in place to prevent doctors from trying to intentionally do wrong. There are zero measures in place to prevent malicious down voting taking place on Hive, and removing peoples ability to participate in the Hive Social side.
There are measures in place to prevent some no skin in the game walking in on a surgery in progress. There are measures in place to prevent a no skin in the game, from trashing a skin in the game account, that being the amount and in-ability of a small account being able to in reality down vote and cause damage to a much much larger account.
There is ZERO ability for a no skin in the game account to protect itself from asshole Skin in the game accounts.
Downvoting doesn't prevent someone from participating in the Hive social side. Assuming by that you mean communication. And you can tell from his subsequent comments that the OP knows this. Downvoting is a redistribution of rewards away from one post to other posts. As it happens, I think the current system on Hive is far from perfect, but until we can make improvements, we operate within the confines of the current rules.
