You can delegate RC to accounts so they do transactions. You don't need to spend them Hive

Farms are when a person opens a lot of accounts and make many posts from each to milk rewards. The accounts you help all have traits of a farm, like the newest toymaster, it only post,and don't comment, and it follows big wallets that don't actively create content. Farms are a popular way to abuse Hive. You may not be running a farm but it certainly looks that way and it is not good.

Rather than helping those accounts to post content that no one reads, it is better to encourage them to be active and engage more on the chain and grow their community rather than huddling together in silo.
