How about a "wedding" excuse, or a more generic "love made me blind and stupid". This one is quite rare and would add some real challenge to the game.
I found the cause! This is terrible. It was my wedding day and I didn't write anything that day. This one was made by a friend of mine, he wanted to help me. Because I read from that date is not my handwriting, not my style. But now I know the reason of ban. That's sad. No one can be trusted in this world. Let this be a lesson to other users, do not let anyone to their work otherwise it is easy to lose.
A similar one - "honeymoon":
Unfortunately mid June was a very stressfull period of the year as i was to depart in the next few hours to a 30 days honeymoon and not everything was sorted. (i can prove and send flight ticket in PM to modo / and admin).
