Given the fact that both r/trees and many other related subs almost got the chopping block last year when Reddit first started sweeping through the subs to clean up their image before starting the IPO paperwork. Only way they remained open was because the sub’s mods agreed to change the sub rules (things like no external URL links, no selling, etc) and sweep all old content violating those rules.

After the API change next month, there will be no way these mods can possibly keep the subs fully moderated to the level required by Reddit admins.

Given the clandestine nature of the subs, I highly doubt that reddit admins will take it over and force it back open - I’m sure they’d rather see it stay closed indefinitely.
