### Solution:
Now for a much more real-world OSINT challenge. First, I started by doing a bit of recon. I ascertained that:
- `AU` in `AUCTF` is for Auburn University ([homeapge](https://www.auburn.edu/))- `AUCTF` is run by members of the `AUEHC` ([Auburn University Ethical Hacking Club](https://ehc.auburn.edu/)). `AUEHC` is comprised of members:	- President - Jordan Sosnowski: [email protected]	- Vice President - DeMarcus Campbell: [email protected]	- Treasure - Luke Gleba: [email protected]	- Technical Lead - Charlie Harper: [email protected]	- Technical Lead - Drew Batten: [email protected]	- [Source](https://ehc.auburn.edu/about/)- `AUCTF` Discord is run by discord users:	- c AKA _c#9643	- FireKing AKA Iamfireking#2686	- JohnsonJangler AKA JohnsonJangler#0353	- Kensocolo AKA Kensocolo#1000	- nadrojisk AKA nadrojisk#6700	- OG_Commando AKA The OG Commando#6632	- vincent AKA FlaminArrowz#5042	- 死神 (shinigami) AKA demarcus1621#6819- `AUEHC` also has a [Github Organization](https://github.com/auehc), which the following github users are a part of:	- Demarcus Campbell AKA demarcus1621	- Jordan Sosnowski AKA nadrojisk	- Vincent Chu AKA vincentchu37- Within that organization are repos for:	- [AUCTF-2020](https://github.com/auehc/AUCTF-2020) Which contains entirely commits by `nadrojisk`, with a pending pull request formulated by `demarcus1621`, with nothing interesting in it. 	- [Their site](https://github.com/auehc/auehc.github.io)	- Past competitions, mostly irrelevant to this challenge.- Reddit account has posted three things, none of which are of use here: https://www.reddit.com/user/auehc/ - CTFTime Team `AUEHC` only has one player, `nadrojisk`. https://ctftime.org/team/82180
With that in mind, I went about composing this table:
| Name              | Discord                                | Github                          | Gitlab                                 | Twitter                       | Notes                                                                                                                                     ||-------------------|----------------------------------------|---------------------------------|----------------------------------------|-------------------------------|-------------------------------------------------------------------------------------------------------------------------------------------|| Jordan Sosnowski  | nadrojisk AKA nadrojisk#6700           | https://github.com/nadrojisk    | NA                                     | https://twitter.com/nadrojisk | All commits to the challenge repo. Prime suspect. Nothing interesting on twitter                                                          || Vincent Chu       | vincent AKA FlaminArrowz#5042          | https://github.com/vincentchu37 | https://github.com/vincentchu37/gitlab | Private                       | Has commits to the site @ https://github.com/auehc/auehc.github.io, https://www.linkedin.com/in/vincentchu37/                             || Demarcus Campbell | 死神 (shinigami) AKA demarcus1621#6819 | https://github.com/demarcus1621 | NA                                     | Does not Exist                | Has pull request to auehc/AUCTF-2020 @ https://github.com/auehc/AUCTF-2020/pull/1 but changes only to README.md, and from private repo :( || Abhinav V.        | Kensocolo AKA Kensocolo#1000           | NA                              | NA                                     | https://twitter.com/kensocolo | Twitter, not much found                                                                                                                   || Charlie Harper    | c AKA _c#9643                          | https://github.com/chharles     | NA                                     | NA                            | Pretty sure this is Charlie Harper                                                                                                        |
The flag was in a repo that was *conveniently* not pinned in Vincent Chu's github. This was in one of the past commits in their repo `AUCTF-2020` [link](https://github.com/vincentchu37/AUCTF-2020/commit/56721948f12e3a76a5316c62ad2bcf47e8119926) [archive](http://archive.today/2020.04.06-032243/https://github.com/vincentchu37/AUCTF-2020/commit/56721948f12e3a76a5316c62ad2bcf47e8119926) made by github user `chharles`, who I have retroactively added to the table above.
