Guys this looks like a bunkum (i dont want to offend anybody,but it looks super suspicious).

Shidoin certificate? Wut , is that typo of shodan?Or rather poor trolling? If he really got pro certificate, how the hell we know about it only in 2018? Also this diagram looks like a trolling - is that B2Bomber kind of?Also link is ofc broken.Adding this up - if we dont get some confirmation, i would rather delete this suspicious info, but if its true, i am deeply sorry already.It pains me that i contest someone pro certificate.
