These host names try hard to evade detection of their IP addresses, in order to scrape content and sometimes break into from web sites. They have specifically scraped mine and so I hunted them down and banished them. Often times the unix host command returns nothing, so research is required. This usually works.
0x667.crypt.gy came back with a host lookup of 94.23.147.30, OVH. I cannot verify this IP address. Research is inconclusive. This guy uses a Microsoft server error code “1639 (0x667). Invalid command line argument” in his hostname.

These user agents, or bots, somehow fool and subvert my .htaccess user agent rules and continue to scrape my site. I’ve looked at my htaccess user agent rule many times and don’t know why. The next step is to ban their IP.
AhrefsBot is a large content scraper that hits my site hard, reads robots.txt but ignores it, fools my htaccess, bot is “Mozilla/5.0 (compatible; AhrefsBot/5.0; +http://ahrefs.com/robot/)”
OVH 51.254.0.0 – 51.255.255.255
51.255.65.0/24
51.255.66.0/24
OVH 151.80.16.0 – 151.80.31.255
151.80.31.0/24
OVH 164.132.0.0 – 164.132.255.255
164.132.161.0/24
Spammers are never welcome, clutter up your comments and are a pain in the arse. They blow through your bandwidth, which then gets your ISP on your tail asking you to upgrade your account type. This costs you money. Here are some dual IP strategies that I found in analyzing my WordPress site’s comments.
Pain in the butt, no doubt, is this spammer. He’s been spamming my blog for the last 6 months and whatever I did in my ban manager, it would not ban. I got mad enough to track him down, figure out how he does it, and hopefully ban him. Take a look at the audit trail he left me in my WordPress Akismet anti-spam filter. I am very thankful that Akismet stopped him from wrecking my blog, and I’ll be more careful and vigilant from now on.

These are telemarketers who consistently call my house here in Toronto and refuse to cease. Few of these have call display info, so I need to research them on the internet. Still, many have no information. The CRTC should regulate this better, as it is very annoying. The “Do Not Call” law should be upgraded to be more all encompassing.
In the mean time I use my Panasonic phone, which has a ban list, but I still get a single ring. My phone keeps track of all our incoming calls, and I track unknown phone numbers. There is some work involved to keep this list current, but the payoff is that you reduce, to a bare minimum, the number of repeat telemarketers.
