Warn
During the MFGG EzBoard days, due to the native structure of the system, there was no "warn" technical system. At that time, because the forums were in their early stages, and the community was almost completely friendly, warns weren't generally necessary. If a member made an error, or defied the rules, a verbal warning was given either in a PM format, or on a reply to their post. Anything past that constituted a ban, which were rarely given.
A Warn (implemented later on in the Invision version) was a simple disciplinary action taken towards members if they committed a minor infraction. They would last for an arbitrary amount of time, though it was later standardized to last 3 months. The Invision board started with 5 warns per user; the loss of all warning points would constitute a temporary ban. Many felt this was too lax, and it was later shortened to 3 warns. The boards used the 3-heart system for a while, before behavioral issues began to surface at an alarming rate. The system was completely rewritten, and warns are no longer used. This new system uses temporary bans, the length of which depends on the particular infraction.
"Hearts" would be restored every three months, however once a year on Valentine's day, a heart would be restored just to be nice.
CCC Five-Strike System
A new system introduced February 9th, 2008, introduced a five-strike system to the CCC. All members start with CCC access; however, this access can be revoked should a certain number of strikes accumulate onto a member: 3 will result in a CCC ban of 3 months, and 5 will result in a permanent ban. These strikes are added as one consequence of a suspension, along with the normal ban time.
