I never heard about Coin Janitor before
It's look interesting concept when I read what their goals/aim from this project.
Is the owner active in bitcointalk?
According to their
Announcement the owner/team of Coin Janitor is not active again
You can contact him in both Telegram or Discord server
Buying dead coin is not a profitable business so they need to generate their income one way or other.
Yep, that's true. But IMO they didn't focus for profit, it's why the price of this coin is not good (
under 1$). They focus about this
Therefore, contributors should also benefit from the value that JAN tokens create for dead coin holders through the sheer force of demand and supply. Additionally, as more dead coin holders join the CoinJanitor community through the buy outs, there will be more JAN holders out there, which should create a network effect that few other projects can generate as quickly.
