considering the fact that they were unresponsive and dismissive and some feedback about slacks bug bounty program from other fellow researchers, I really didn't think 180 days was worth the wait so yeah I chose my own. I am at the liberty to do that just like how slack has the liberty to ban me from their program. So yeah your guess is good!

And it's not only me who has had such a terrible experience with their program. I know atleast 3 different researchers who have reached out to me to tell me that they have gone through the same experience. They prefer not to speak out. I did. Period.
