Thanks for trying but I already got a tipu upvote without a curator, it seems.

wow you are very popular.

No, it shouldn't be about popularity.
I don't know why it's happening.
It seems some peoples are getting small upvote from tipu without the comment of a curator.
Besides... I'd get a bigger upvote from your curation if it was normal.
It seems abnormal to me.
Thanks for your understanding.
