toxic indeed - I somehow ended up in IRC channels as a curious, lonely ten year old with a computer and parents that frequently confined me to my room with nothing but a computer, an internet connection (which they thought could only be used for email), and books. One of my more formative experiences was getting my pc pwned, getting so upset about it, I resolved to learn everything I could get my hands about it in my teens. Never got super far as some did, but that curiosity sparked in me a drive that has lasted nearly 30 years now.
Which meant I now knew what port and password the sender was expecting to connect to me with.
However, most of them were skids, and had inadvertently executed their own dropper on their own machine at some point. And I knew their IP from the DCC.
Which meant I now knew what port and password to connect back to them with...
edit: Ahh, EFF privacy badger. Turned it off and now I know what you're talking about. With it on I didn't see anything :)
We had a hard policy of never going "I'll connect to it and remove it for you." Sure, it could be quicker, but it would also be legally problematic, especially if the person seeking help was actually an impersonator.
[0] I admit, I harmlessly pranked one very close friend with a CD-ROM tray that kept moving "on its own". And pointed out some weak passwords to school IT...
I’m not even sure why I had them as a kid, I never managed to actually use them.
