It probably was due to:

As I moderate a lot of posts I honestly cannot remember the exact reason (or even if it was me), but rest assured we are tightly watching that our forum quality is the highest we can get.
Usually we did sent a message to the user if a post was deleted with the reason, however currently the messaging system is not back up and we are working hard to get things right in that respect.
But yes we are tightly moderating this forum to upkeep the quality and language standards we have set.
Sorry for any inconvenience this may have caused.
