I've had people reach out to me through other channels to explain things that they didn't want to put on the blockchain, mostly background on some of the politics of this peculiar microcosm we call Hive. Sometimes I go to Discord for a bit more privacy and ease of comms, but that's more a channel for if I need it than one of active communication. Then there's some conversations that just need to be away from electronic devices entirely, likely over a beer.
I think I've already asked you my questions, over the years there's been a few that you've rather smoothly managed to not answer. Sometimes I can take a hint and will not call further attention to them but we've already got a nice list of 'over a beer' topics I believe anyway.
WhatsApp eh? Signal is the only messaging app I have and that's more a holdover from 2020 than something I regularly use.
Yeah, I sometimes completely ignore questions people ask as answering could either bring more or simply cause me to be so cryptic the answers would be unsatisfactory to those who ask them - Having said that, some read between the lines, as I believe you have in some case, and that's ok, I don't mind; most aren't as savvy as you though.
Signal, I'm not sure if I can get that but I use Threema (a paid app) and it's pretty good for comms requiring a more secure platform. How secure is any of it though I guess, not very I suppose.
