No thank you. Please do not do that. I almost never have an interest with chatting 1:1 with a stranger after they ping a channel ostensibly devoted to a topic. If it's someplace where they're (justifiably) expecting help and support, then I'll provide the help and support there - where other people can also help and check my answers, and where others can find answers to the question there.
Person: "hi"
Me: "Hi, what's going on?"
Person: <DMs me about something>
