代练

代练 grew into a multi-billion RMB gray industry in China around games like LoL, Honor of Kings, and Genshin Impact. Major platforms (代练通, 比心) brokered tens of millions of orders. Tencent and other publishers crack down via account bans and lawsuits, framing 代练 as a violation of the user agreement (违反用户协议). Compare 陪玩 (péiwán, 'paid play companion'), which is legal and just plays alongside you.

代 (dài, 'on behalf of') + 练 (liàn, 'practice/grind'). Same 代 prefix as 代购 (dàigòu, personal-shopper service), 代驾 (dàijià, designated driver). Distinguish from 陪玩 — 代练 = boost my account; 陪玩 = play with me.
