Tried entering some text into the bio field for the clan I'm creating, but apparently it includes an inappropriate phrase.
"IceboltzAu is an Australian clan created for the best of the best. Age or Gender mean nothing, if it means you can bring a competitive aspect to the team. If you're even considering applying for IceBoltzAu, You better be committed soldier! See you on the battlefield, Freeze them in time."
My guess would be that you used proper grammar and punctuation. I can remember in the early days of Elite, commas would often trigger the inappropriate language filter. They eventually got it fixed but it was quite annoying at the time. It may very well be something similar this time that is causing the issue.
