On "your forum" it is none of their business,and that is your prerogative. On my forum I usually make it everyone's business, and that is my prerogative.
Your making a lot of unnecessary work for yourself, but again your prerogative. On my forum, rude behavior, spam, harassment draws a ban for first offense. Whether permanent or time period is tailored to each situation. Warning points or verbal warnings point you out as a softie IMHO.
I am not too fond of the LIKE button, but concur, that it is rather useless for anyone if you cannot see who 'liked' a post. The like would be strictly for the reader, but should of equal, if not greater interest to the poster.
