You were not banned for accidentally hitting the filter the first time- you were banned because I specifically told you NOT to repeat it in chat, and you spaced it out to evade the filter and put it in chat.
Here is the issue, with some of the other random chat removed to make it more clear for you (edited with *** to remove the filtered word/abbreviation):
[20:22] <+FamcraftIRC> [m] 09Icy_Flow: ***
[20:22] <+FamcraftIRC> [m] 09Icy_Flow: what the...
[20:22] <+FamcraftIRC> [m] 05Admin: RubensCherub ❤: Icy_Flow- no
[20:24] <+FamcraftIRC> [m] 05Admin: RubensCherub ❤: Do not
[20:24] <+FamcraftIRC> [m] 05Admin: RubensCherub ❤: Type it again
[20:26] <+FamcraftIRC> [m] 09Icy_Flow: i typed in * * *
This is called evading the filter. If a staff member asks you not to repeat something in chat, please do not repeat it. We all knew what you said, we just wanted to keep it out of chat.
If you understand why you were banned, please reply to this post and we will get you back on the server.
