Choose a name that start with an I such as: Impossible, Ignorant, Imp then replace the I with a lower case l and no-one will notice, I have a name like that and When people are looking me up I always have to tell them it's an L
names like ILILILILLILI are so obvious because the person knows your using Ls and Is and when an l and an I are next to each other it's easy to distinguish between the two
