I am aware of 4 separate deals this manufacture is doing, or has proposed.  Each of them have been for 5k per miner.  For them to all of a sudden be $6750, when I know the other 3 of the 4 other deals have had time extensions to pay, is very unlikely.

I have always appreciated this mining community because we have mostly had each other's backs.  This sort of stuff is distasteful if true that there is built in costs not discussed with the community.  If you feel your time is worth a few extra miners, then say it and disclose it.  I don't think any of us would fault for that.  As soon as it is hidden, that is when trust is broken and we start to devolve into just another shitty community.
