So far from what I can gather

1. Obari is an alt of Sakanwa as proved by the transaction history by both accounts using one exchange Bitcoin address at one point

2. Again Obari forgets to login as Sakanwa and makes a post in a loan thread where "Obari" never took any loan by Sakanwa had an outstanding loan

So Obari = Sakanwa

3. Sakanwa and hashrateproducts post in one campaign thread using the same bitcoin address that sakanwa has always used.

There is also proof that  hashrateproducts is a hacked/stolen account

So Obari = Sakanwa = hashrateproducts (the person who stole or bought that account)

Furthermore, hashrateproducts is linked to a group of bounty cheating accounts, some of which are even already banned
