In answer to your original question, no, Im afraid it cant be removed permanently. It happens occasionally if anyone's character has a family member called Ju
lie, Lau
ren, Je
nny, In
ga or Ca
rys (granted the last one is less likely - and thats me by the way

)
As Alice said, the way around it is to type the name, then put your cursor somewhere in the word and add italics - it doesn't actually italicise any part of the word but it confuses the filter so it doesn't change anything. It could be worse though - I play Hannah Abbott, and when we had an admin called Hannah...well you can guess the rest

Sorry if we confused you!
