Pump-and-Dump Source on HK-China Nasdaq Listings for Barron's

Reporter looking for HK and China pump-and-dump sources Hi there. I'm a reporter at Barron's working on a story about pump-and-dump schemes by Hong Kong and China-based listers on the Nasdaq. I'm particularly interested in the investment banks, lawyers, and auditors facilitating these schemes. If you're someone with inside knowledge of these schemes, either as an onlooker or as a victim yourself, please reach out via private chat. Any kind of non-public paper trail—memos, messages, screenshots—is particularly helpful. Thank you.
