Instagram Suggestion for adding Instagram username filtering

I have a suggestion for the Instagram category
These filters will mostly be useful for people searching for usernames.
For example, a username filter system can be created in the filtering section as follows:

Filter Instagram Username Letter And Other :

4 Digits
3 Digits
2 Digits
/
Usernames Containing Only Letters (does not contain numbers or punctuation)
/
Usernames containing only numbers
/
Special Name
