Hashtag relay, welcome back 
We Japanese were worried about your presence! Glad to see you again 
@fell
There are accounts that automatically and manually boost posts in response to the hashtag "hashtag relay." It had not been functioning recently and several Japanese were concerned about the health of the operation and other issues.
@caprica0963 Ohh! I have seen those a few times. Good to hear they are back. 😌
@caprica0963 What is hashtag relay?
