Hi.
I would be careful auto upvoting all the comments. Many of these accounts are comment spammers, some already blacklisted by steemcleaners.
They spam on posts by curators that always upvote the comments to fish for rewards and/or get destroyed reputation back.

And many accounts with similar names to these.

Any account with reputation lower than 25 is likley to have been flagged by us for some abuse too.

P.S. Please don't upvote my comment
