Blacklist suggestion

According to this the FireHOL list has a low false positive rate.

Found the source list here:

Direct link here (this is what we should use):
https://iplists.firehol.org/files/firehol_level1.netset

And individual lists that make up this one are here:

The only problem keeping me from implementing this now is that it contains CIDR ranges. We can't even just expand the ranges to individual IPs either since some of the ranges are for non-routable or reserved IPs like 0.0.0.0/8 or 224.0.0.0/3.

• One option would be to just ignore any entry that contains more than x IPs in a range and expand the rest.
• Another option would be to add logic to store ranges and check if an individual IP is contained.
