Yeah, I hit the dark web every now and then. It's primarily a function of curiosity coupled with my deep respect for anonymity. I decline to purchase anything available there because I don't trust the ecommerce security of the environment.
Fool me once shame on you. Fool me twice shame on me.
My issues with TOR nodes surround log entries I have amassed whereby denizens of this space attempt all manner of exploits as though it were populated by nothing but criminals and riff raff.
Consequently I have written filters to exclude this traffic from my servers as a matter of self preservation. Some of the antics I have encountered over time have been amusing. Others very disturbing. The bulk of them all sophomoric and lacking technical merit.
So by all means, if you like the idea of what TOR represents, as do I, then go for it and hit the dark web with every onion router access at your disposal.
If you sense that the lack of character and scruples in the population, adequate backward compatibility, and feel a general abandonment of too much in the space then I would stay away.
Right now I'm fairly ambivalent. I don't like some of the little hacker idiots who think they can walk all over me. They are the reason I don't allow TOR nodes on my server cluster anymore. This policy was long in coming and the product of innumerable attack packets and injection attempts.
I do go onto TOR space sporadically but find the available content to be lacking with browser failures and stale URL cache in the onion search engines being the predominate experience. It's as though the space is designed for those who wrote it and that's it. Not being a back door netizen too much of the dark web fails to operate or have destinations to suit me.
