This leaves a very short window of opportunity between Ralph's DM's on twitter to drop the dox, AND potentially, a short span of time to actually compile the dox, if not precompiled. But the dox is simple, so it could be compiled quickly and easily.
The only people who could have seen Akira's post on patron are other patrons and Ralph. Now the chances of another patron just stumbling on his post on that dead community tab are quite slim, HOWEVER, it's likely that Ralph receives emails every time a post is made there, and it's likely he would have seen that posted on his patreon page, and from that, he could have easily connected the name of the patron to Akira. This would then be confirmed easily with ONE simple Google search.
That makes even a quick dox compilation for Ralph extremely easy. Even further proof, is that despite Ralph saying this dox was EASY, he's pointed everywhere EXCEPT his patron page. I find it hard to believe that in nearly 2 weeks, Ralph hasn't seen this post, so it seems to me, as if he is trying to direct attention anywhere other than his patron page, where it appears there are multiple people essentially doxing themselves all over. It seems like Ralph would rather point to the instagram page he found with Akira's name instead of the information right under his nose.
