# Syntax is as follows: 
#   * Everything from a "#" character to the end of the line is a comment
#   * Every non-blank line is a regex fragment which will only match hosts
#     inside URLs

# A lot of spam is coming from these non-English ccTLDs. 
# Do you think these may be too broad?
\.ua
\.cz
# \.pl - blocks URLs starting with PL (e.g. Gamespy's Planet network) so disabled for the moment

# By default, "create a site/forum/profile/blog/whatever" type sites are 
# not notable and often used to spam. Nothing good can come from these.
