/****************************************
→ the program is case-insensitive
→ split the usernames with a comma
→ put a * in front of a word for wildcard (only in the blacklist!), it will find the word no matter its position in the username (example: *vevo)
→ on line 128 you can change the pages in which the search is excluded
→ VERSION 2:
# blacklist editor changed
# whitelist added
# no need to refresh the page after changes in the blacklist/whitelist
<!> please report any bugs
