What is the best way to deal with a member who posts all the time in a buy/sell group (about 500 members) of which I am an administrator on Facebook?
I have asked them through Messenger (politely) to consolidate their posts and to delete sold items. This person politely agreed, but then only did a partial job and still left a very messy situation.
This person is an acquaintance that I have only talked to a few times in person.
I am familiar with the technical controls in place on Facebook. That's not what I want to do though, the rules are sufficiently broad that I can't find any specific rules they are breaking so banning or blocking won't really be an option. I am looking for interpersonal solutions to persuade this member to improve their behavior.
How can I persuade them to quit filling up the timeline besides blocking them from the page?
