I enter a large number only because I don’t want to worry about the user again – not to show on a grand scale how much I dislike them.
I guess something like 3-5 years sounds better. My intention is mainly to make and convey a firm decision (this user is – for the foreseeable future – gone) but leave the option that perhaps down the road if the user matures and reaches out to the administration they could come back. Setting a specific date clouds the message but I’ll roll with it for now.
■■■■ = ?
I give pretty straightforward reasons (user spammed, user continually pushed discussions off topic, et cetera).
