>>6 That's simply absurd, we're essentially just telling everyone to make a throwaway account that will most likely never be used for anything other than following the main Dollars account.
I hate to state this one, but I'd skim through Dollars Discord server's member list to look for someone rather than anything else (even the email database, since they're filled with mostly dead emails anyway). And the members that are listed there were actually contactable as soon as you found them.
And last but not least, the Missions part. Posting mission content daily or weekly boils down to how dedicated you are to the act, and how much are you enjoying it. I say this with absolute confidence, because you're not the first one to propose something like this and likely wouldn't be the last either. Our numbers are dwindling, and most members in the current generation aren't willing to be invested with the community's effort when it is all we actually need to make something actually succeed (somewhat) even if it only enabled us to take a little sip of victory.
But in the end, I'm biased against using Instagram. Maybe that's why I desperately want you to rethink of the idea, then again I can't hide the fact that lots of people in the past had actually proposed something only to give up shortly due to burning out from the lack of community support. Everyone envisioned a different version of Dollars that they want to materialize, perhaps that's why we never got anywhere with whatever we're trying to plan out.
