It's amazing how little interactions add up to a reputation. You banned me from a minecraft irc channel when I said that the leap second was causing issues with some minecraft servers. (see https://www.wired.com/2012/07/leap-second-bug-wreaks-havoc-w...) since then I avoided a collaboration opportunity with you for this purpose. (Mediacrush-related)

Bad experiences like this add up, and it's very hard to repair a broken reputation.
