If these things are left unchecked and properly not conveyed how serious of an issue they are, they'll grow uncontrollably all over the ecosystem to continously damage it. If it's not too much rewards then please don't accept them on such posts, it's easy to forfeit them through beneficiaries.

Manual curators being picky about who gets bigger upvotes based on self-interest is the same as autovoting people if they're delegating your way or holding some tokens of yours. Using layer 1 curation to prop up the value of layer 2 tokens is against hive curation, I know you're not excessive in that regard but it's still unfair towards other curation projects and stakeholders that focus on everything else that should be important in curation rather than self-interest.
