You can bypass the chat filter easy. This is how it works.
You want to say something to a person but you know it will be filtered.
Step 1. Open the chat window.
Step 2. put the filtered word in a line. I am going to fuck you up.
step 3. before you type fuck you do this alt+255 this will add up a undetected char infront of fuck
and it will bypass the filter.
step 4. Fuck that guy up xD.
I hope i helped you guys out with bypassing the league of legends chat filter. Know that cursing is not good but i know some of you guys just want to have fun.
Hereby, have fun with League of Legends uncensored.
