Yeah, OP got a huge payout for sharing a link. While steemit.com fails to offer a max-payout UI option, here are a few workarounds:
- Keep posting, let it self-correct. If the reward really is too high, it's not like it's the OP's fault. People should pay attention and fix their curation logic.
- OP can use Decline Payout every so often so that over the course of many days, OP's payouts are limited.
- OP can start posting with streemian.com (Scheduled Posts) and set a Maximum accepted payout in the Advanced Options.
- OP can use my ruby script to post, which also allows OP to set a max payout.
