Rule: If a user requests that you cease contact with them, cease contact. Do not reply to, quote, @ or “like” their posts.
Yes, we have a mute function, but it shouldn’t be up to the person who said “stop” to do all the work.
And yes I include “likes” and yes, I think behaviour in other places can be considered if we can show that a) it is the same person and b) it supports evidence of patterns of behaviour shown here.
Most of us would agree that if you told someone offline “do not interact with me” and they started sending you flowers, it would be wrong. Most of us would agree that if you knew this person from work and HR said “knock it off” and they started showing up at the gym and leaving flowers, that such behaviour would be wrong and claims that “the gym isn’t work, so stop picking on them” are specious. Digitization doesn’t make it all better. Saying “it’s just likes” is like saying “it’s just flowers”. No, it ain’t, and we know it.
