SE is always SE... Rage inside... :/

Yes. If they need more testers due to lack of responses, they'll send for more testers.

They are looking for bodies to follow instructions for their testing effort. First and foremost.

the problem is not someone did not get invite event though they apply and have active account... but someone who applied with inactive account...do you think it is working as intended??

I do not know the particulars of the agreement within the email, but SE is looking for a sample population of testers. If they AGREE to partake in the testing for Alpha, SE is happy. If there are not enough responses, SE sends for more. If people are breaking the agreement SE responds accordingly, (bans and legal action) and send for more testers.

This mysticism about game testing is why actual game testers get terrible pay and little in the way of benefits, despite playing games to find bugs is a hell of a lot more tedious than you think, especially when your job depends on it.
