The network security people I know stopped bothering publishing attacks on I2P's directory service--which was(/is) in fact subject to eclipse attacks--because I2P didn't seem to care to fix the issues. Here's a great paper.
Great... are the issues getting fixed? The point I was making about I2P working so poorly that some people have given up trying to help--in addition to specifically noting that eclipse attacks do, in fact, affect the design of I2P--doesn't seem affected by "there exists people who still spend time demonstrating I2P doesn't work well" ;P.
Maybe those you know stopped, but others didn't: https://geti2p.net/cs/papers/.
