Lately, people who once left the membership keep coming back! I’m happy to see them return—but if they’re coming back anyway, I wish they’d just stay 😅

Top 7 traffic sources for my channel — and guess what’s on the list? ChatGPT 😂 People say “ChatGPT solution” on my posts in LeetCode — but I tell them: “Check my LeetCode history — I’ve been solving it this way before ChatGPT existed.” I will say: “ChatGPT learned from me.” 😎
