Continuing with this series, The Discord server has only 1 channel where mcha4ker1337 and martini-craft were chatting, checking the messages from the beginning we can see that they played a Chess game :

In the bottom Left we can spot martini-craft’s username,from there we can find his profile on chess.com.

Checking the profile and nothing was really interesting there, hopefully before trying anyhing wierd or complicating it, I took a step back, scrolling down a little bit on Discord , this was interesting u have some sensitive info exposed on you're profile

might want to change that ooohhh good catch! I removed it, thanks for the heads up

gotta keep my opsec on point! so right away to Wayback Machine, https://web.archive.org/web/20240520023121/https://www.chess.com/member/m4rt1nicraft

Cool we got martini’s email, I spent some time here trying different tools and tricks to find any info/account related to the email. After a while I came across a great tool :

and we have some progress, we got a link to Google Calendar :

Then it was just straightforward, check the Secret Memorial Day Gamer Event, the Instagram profile https://www.instagram.com/tf4rc_1n1tr4m_733132/ and get the Flag.
