This flower, Coreopsis lanceolata, comes up every year and is beautiful. It is very successful at propagating and spreads quickly. I like this in a blooming flower, but not in a weed. It has literally taken over.

I had a bit of a search for the actual name: Lance leaved coreopsis.

About 5 years ago a neighbour gave us a clump of a few flowers. We planted it in our front yard that gets full sun. It has grown and expanded every year, irregardless of a hard or mild winter. While the roses are temperamental and need care, the coreopsis needs nothing.

mediaworksit.net: Research, Ban

free-109-108.mediaworksit.net has tried to crack my security so I thought it appropriate to track them down.

The host name only provides the third and fourth octet, leading one to gues the first two. As they have not repeated the third octet you will need to ban larger ranges.

7by7.de Content Spammer: Research, Ban

tor-exit-node.7by7.de spammed me today, so I decided to track them down. There is not much on him, but he is a tor exit server.

It is too bad that tor exit servers are used for spamming, as many sites will ban them. Banning due to spamming really defeats the purpose of tor. The best intentions result in misuse.

yota.com.ni, Part of Semalt Botnet: Research, Ban

wimax183-11.yota.com.ni hit my site as a part of the large Semalt botnet that started with keywords-monitoring-your-success.com and free-video-tool.com campaign, which I have already banned. That botnet was huge. They involved virtua in Brazil as well. Finally that campaign ended and they started with fix-website-errors.com and buttons-for-website. buttons-for-website is a really old Semalt SEO botnet campaign.

10gbpsnl.greencloudvps.com hit my site looking for security weaknesses, so I thought it wise to research them and send them packing. They are a VPS, so I’ll never find the actual intruder.

hukot.net Tor Exit: Research, Ban

108-36.hukot.net seems to be a Tor exit server. While I am all for the philosophy of net privacy, these Tor servers more often than not are used to content spam me. As a result I ban almost all of them. It is human nature, I suppose, to take something that should be beneficial and, using selfish and personal reasons, turn it to a tool of the bad.

Oh well, who am I to judge. This is my site, I ban content spammers, and I therefore also ban Tor content spammers, exit or not.

hukot.net seems to be an ISP from the Czech Republic.

ubernet.com.bd: Research, Ban

host-64-166-83.ubernet.com.bd was testing my security, so I thought I would out them. ubernet.com.bd is an IP telephone and ISP, out of Bangledesh.

Pattern:
This guy seems to have an older and a newer pattern. The older pattern starts with 220.47 and then appends the last 2 octets of the host name. The newer pattern starts with 45 and appends the last 3 octets of the host name.
