For the clan with groupid=2690150 it is not possible to edit the "About us" field to contain the word smile. After submitting it results in the error message: "The external platform string validator rejected one of your inputted strings. Please locate and remove all variants of "smiie"." The string "smiie" isn't even contained in the content that was submitted, it is instead "smile" that the validator rejects. (And i feel like you should have a proper place to submit bugs to your ticket system. At the very least i can't find it.)
