Downsizing wordlists.

[DDNK]

I'm looking to expand my techniques of Downsizing Wordlists, and removing useless passwords for cracking efficiency. 

I usually do the following:
Remove duplicates & empty-lines.
Have a minimum length of around 6 or 7
Find the emails, and perform @.* (Hashcat@hotmail.com > Hashcat)
Remove IP-addresses.

I'm thinking of removing all numeric-only passwords, hashes/salts that may be within them, and finally removing all spaces within a password. 

Any feedback / ideas are appreciated.

I like the idea, I'm using the same techniques for my wordlist. However I'm not removing them entirely, I just sort them out to a dedicated file.

1. Sort out all words < length 7
2. Sort out emails
3. Sort out words that include chars < 0x20 and > 0x7f
4. Sort out pure digits
