It is always a bad idea to allocate full HP to an account unless the person wants to go on vacation and wants some returns actively.
But, I see it as norm in getting upvote by delegating HP or buying their costly L2 tokens, and it works great for many accounts. But, there is good side of it as well that helps small accounts to stand on their feet, I see some projects just revolve upvote on selected people with highest reputation and ignore users with low repo, this behavior causes small users to invest in such project to help them build.
yes, they build their HP getting "free" upvotes, but they lose the potential of growing followers and being appreciated by the community for supporting others...
