Good to see some negative sentiment building for the usage of Slack in the crypto world. Slack is great for some things, like Internal team communication of a larger company, but I don't know how it got so popular for cryptocurrency. Channels can become a nightmare to sort through, and the lack of tying things to a phone number makes mass creation of accounts even easier. Decided to not get a company Slack early on, because the moderation appeared like too much of a nightmare.
Same troubles on Bitcointalk, Newbie Spam and such. However phone numbers are so old fashioned surveillance state, aren't they? I am not interested in any channels that require a cellphone to enter. And my smartphone from china got bugged by its manufactoring company even before packaging.
People who invested livetime in their accounts are legit. Maybe there could be a currency for that. A forum coin?
In a way there had been crypto projects focusing on attention economy, currently up&running: Steem.
Seems Slack got an edge above Steem in the ways of beeing dirt cheap, so people flocked to that.
