While right now they don't put attention on your duplicate posts using multiple accounts, the problem might come when both your posts get significant upvotes (let's say at least $0.5 each) where you would be accused not by plagiarism but by reward farming, unless one or both of your posts have declined or burned payout. 🤔
If you need additional Hive Power, you can request 15+ Hive Power delegation from @giftgiver for each of your Hive accounts. 🤔 The delegation expires after 7 days, but you can easily renew the delegation again (assuming @giftgiver has enough Hive Power to delegate). 🙂
