My Grok Bot has unfollowed 213 accounts for me since Oct 16, and I can tell you why it dropped every single one.
I follow 6,967 accounts on X. I never pruned that list by hand, so I handed it to a Grok Bot routine that runs twice a day, at 09:40 and 14:40 Taipei time.
The rule fits in one line: unfollow only if the account doesn't follow me back, hasn't posted in over six months, and has never interacted with me. Since Oct 28, before each unfollow, the bot also opens the profile page again and checks the last post date there.
Each run now stops at about 12 accounts. If the rule ever goes wrong, a batch that small costs me a dozen follows before I notice, not a few hundred.
Every unfollow goes into a log as handle, reason, and last post date. 89 of the 213 went quiet somewhere in 2023. A few were worse than quiet, like an account posing as exchange support that pushed people to a Telegram helpdesk, and a memecoin account impersonating Elon Musk.
The bot also writes down who it kept. KOLs who went silent stay, project accounts stay, and an account whose only post has no readable date stays until I decide. This morning's run held back one account for exactly that reason.
That log is the whole reason I trust this job to a bot: 213 unfollows in 17 days, and each one has a written reason and a last post date I can check myself.
Tether froze 378.7 million of the USDT stolen from Binance's Tron wallet. The 234 million that slipped past the freeze became 638.2 million TRX, and TRX holders are the ones carrying that bag now.
The race was short. Around 20:22 UTC on Oct 29, a Binance Tron hot wallet sent 612.7 million USDT and 46.4 million TRX to the attacker. About 24 minutes later, a second wallet started buying TRX on SunSwap, TRON's main decentralized exchange, at an average near $0.367. @tether blacklisted the main wallet at 21:09 UTC and two more by 21:21, but roughly 38% of the USDT had already turned into a coin nobody can freeze.
That rushed buying pushed the main SunSwap pool as much as 18% above exchange prices, and arbitrage bots selling into it collected millions. Now the flow runs the other way. One tracked attacker wallet has passed on more than 630 million TRX in over 1,000 transfers. Meanwhile the Binance TRX/USDT pair touched $0.302 in the last day, under its $0.3315 pre-hack level.
Size is what matters for holders. At $0.308, those 638.2 million TRX are worth about $197 million. Binance's TRX/USDT pair traded $75.4 million over the past day, so the bag equals roughly 2.6 days of that volume. Even sold slowly, a pile that big leans on a market without much spare demand. The 18,270 BTC from the same hack hadn't moved as of Saturday, and Bitcoin's market can absorb that far more easily.
A stablecoin freeze protects the issuer's token, not the chain it sits on. Nobody, @trondao included, can claw back TRX once it moves, so the escaped USDT didn't vanish. It became TRX supply.
TRX now sits about 7% below its pre-hack price, and the TRX the attacker bought still equals more than two days of Binance spot volume.
