Caution

GH user longhutianjie is performing a supply chain attack!
🚫 BLOCK user immediatly and report him to Github 🚫

The first step is getting rid of "first time contributor" status.

The user has manually added the message "Signed-off-by: " to make the commit
look more trust worthy. User has opened similar PRs in all these other
repos in within the same hour:

• FIX: fix shutdownCancelProfitOrders json tag c9s/bbgo#1731
• chore: remove repetitive words crypto-org-chain/cronos#1566
• chore: remove repetitive words ethereumclassic/ethereumclassic.github.io#1579

Furthermore I'm pretty sure this is the same person or group as github.com/vivoxfold3,
who tried performing the attack against these repos, with the exact same style:
Manually adding the message "Signed-off-by: " and making trivial contributions
to many crypto libs within the same hour:
