Someone is sending a message like this: 'You have won in the ongoing Plurk lottery.' It's a scam and there's no Plurk lottery. If you have seen this through a private plurk, please do ignore it and ban it.
Hong Kong and Indonesian plurkers will be respectively auto-following 2 official accounts PlurkHongKong and PlurkIndonesia with local community manager support. You can still unfollow it if you don't like it.
