I had to ban several usernames (or was it one person using several usernames?) today. Remember the rule listed on the About page:
It's worth noting: within a 24 hour period, the intent for HBIT mining is per-person, not per-username. If users are suspected of abusing this, they'll be contacted and possibly blocked.
Reading back over it, "...contacted and possibly blocked" might read too kind. Perhaps I should just change it to say "blocked."
Personal side note: It's actually kind of sad to see people playing games, wasting others' time and abusing their trust, just to swindle a few pennies.
:(
