Interesting, you don't suggest Bitmain use
this thread to post about all their new offerings. How many product threads does Bitmain have? More than two...
Because
1) Spondoolies themselves chose to announce in their own thread
2) The thread is controlled by them, not a random person
3) That allows them to control their own information and change it if/when it becomes outdated
4) The link in this OP trolls the email campaign tracking
5) Bitmain has magnitudes more individual customers than Spondoolies. Spondoolies prefers to sell a tonne of product to one guy, Bitmain prefers to sell a product to a tonne of people.
Bitmain has probably 10 major threads that pop up when important:
S1, S2, S3, S4, S4+, S5, S7, C1, U3, Bitmain.
