New items added to the game during the season will be banned until the next season. Modification of weapons will be evaluated by the administrative team. Taunts that are silent and/or toggle-able have been banned. Please note, the Season number on the whitelist.tf page may not correctly indicate this season, but it will always be the most up-to-date version of the whitelist, the Season number is just somewhat as version tracking and to indicate when the last set of changes were made.
It is the responsibility of the player to not use these weapons in matches. The whitelist not loading or loading incorrectly is not an excuse for using banned items.
