Usernames should be lower case
There can be the same username with different cases And when accessing the profile it shows same way, example:
- demi -> /profile/demi
- Demi -> /profile/Demi
- dEMi -> /profile/dEMi
- demI -> /profile/demI
Ideally there should only be 1 type of demi. Which can be whatever version of the capital/lowercase letter. But the profile link should always be lowercase regardless.
