I want to make sure i understand this correctly. This is going to be like a customer loyalty program is that correct?

Basicly yeah . Sether is all about trustworthiness and transparency ,Every thing is explained on the website . Brief explanation on what will sether provide :
"SETHER will use smart contracts to  bring transparency, thus trustworthiness, but are isolated from social networks ,It also bring social networks data, intelligently analyzed, into the smart contracts. Integrating smart contracts into your marketing strategy offers your business an amazingly efficient and transparent crowd-powered advertising engine, providing your clients with a new way to interact with your brand, while cutting supervising and monitoring costs at the same time."

That is a very cool strategy that will be attractive for a lot of investors, also for me, I think it is very promising and so I joined in this project and hope I can get some free coins.

This is a good promote plan, which must bee successfull and execute this purpose. Beta test this coins for free gives to us opportunity to try this amazing service. Will try out. 

first of all, I don't trust John Mcfee.
So we can understand from his twitter that sether is not for people who are planing to sell after few months, but that's the case with all ICO, we have to hold them for long term and wait for right moment to sell out.

If i dont have wrong, i think we cannot mining SETHER at now. But i know we can mining at ERC20 contract if our dev provide this function. Could we mining SETHER?

Will just wait for the future updates. If they don't respond again go and contact there support or P.M the admins.

Excuse me Sir, is there any bounty campaign ?
looking forward bounty of this project

I read somewhere in twitter that he get a quarter million dollar for those kind of comments in twitter. I mean why someone like Mcafee should make in twitter those kind of comments? It is probably possible.
