Since you ping me, I will reply, but let me be clear please. I'm not defending hitsquad, nor am I fan.
I'm just amazed that people have such strong opinions and complaint, entitlement, about "free" service (that costs us time and money, sure, but doesn't every single GA in some way). Indiegala feudallife thread is like this too, where people scream for working key like they deserve it, when it is supposed to be for "fun."
The suspension thing is hitsquad attempt to catch bots, using automated message send. People tried to set up messages sent in 1hr interval, and he knows this, so he is testing timeout if not reading the screen. Is it good solution? Maybe not, but it sure does catch people who are stealing rewards from other people actually present. Have to admire how owner is trying, even if it's not a best way. Of course, this angers anyone who is attempting to set up chatbot and farm 50,100,200k drops for their greed.
After all, one game is not enough. It's never enough, is it? "Gotta catch 'em all"
