I agree that there are some things here that don't make much sense. If you catch somebody abusing the blockchain, the first thing would be to warn them that what they are doing is wrong (often they are not even aware of it). If they don't change their behaviour, we could give them a downvote and warn them again of the repercussions. In such a situation the person would probably stop his behaviour. However, it often doesn't occur like that. Offenders are downvoted until they quit hive...
