We are working as a partner for IOST to deliver news to the Korean community on Steemit.

Well that would explain the identical posts that I also found on IOST Facebook and other blog post, it would not explain why these posts are voted in late and seemed as it was just a means of farming rewards.

At the same day of the first downvote, we talked to one of ocdb’s member, and was told that our posts were effortless and worthless.

This is not true, I nor @anomadsoul have talked to anyone of you about this account. I wrote a post about this and my reasoning for the downvotes which just got downvoted from you and nothing else was said: https://steemit.com/downvotes/@acidyo/the-iostkr-account

I'd prefer some communication next time as well over mindless retaliation and downvoting (especially when the retaliation occurs on random posts that may not deserve the downvotes). Thank you for writing this post in english as well.
