Spam haven boards include (but are not limited to):
Bitcoin Discussion
Mining speculation (not as much)
Technical Support (not as much)
Economics
-> Speculation
Marketplace
-> Gambling
->-> Gambling discussion
->-> Investor-based games ("ponzi alert" spam)
-> Lending ("you need collateral" spam)
-> Service Announcements
->-> Micro Earnings
-> Service Discussion
Trading Discussion
Meta (certain threads)
Politics & Society (certain threads)
