He has previously had two proposals.

One was Vessel, an app that enabled easy management of multiple Hive accounts. He did not fully deliver on this one, abandoned it. As far as I know, it was patched by Hive account@rishi556 and a few others later to even continue working and/or addition of additional features.

His second proposal was basically this, promises of SMT (Hive-integrated L2) and core development, it got funded. He hasn't pushed a single proper commit or any of the promised features to Hive repositories and completely disappeared. He went no-communication with everyone, simply sold all the HBD he got from the proposal, and powered down every single Hive Power he has on his account. Even forgot to update his witness, despite being Top 20, causing him to affect the chain negatively.
