Simple suggestion - a pot that those interested in collecting the 3k credits for a durden spawn can contribute to. 

-Player starts a pool & names the durdens. 
- Announcement goes out to all users stating a new pool for "Nameof Spawn" 
-Players then donate directly to the pool
- User who starts can toggle "Start after 72 Hours regardless of Pot" or at 72 hours credits get refunded

pros: 
No more fucking mails about spawns 
No risk of being scammed by skeezy fucks
NO MORE FUCKING MAILS ABOUT SPAWNS

Cons: 
You'll have to code something
I won't have a blip of annoyance at a mass mail
I'm sure contrary people will think of some
