Yes, as I was saying, since 2021, several dynamics have been developed to encourage power ups. The most effective was the club approach. If you had 100 Steem, the following was applied: club5050 (you activate 50 Steem and withdraw 50 for a month); club75 (you activate 75 Steem and withdraw 25 during the last 2 months); club100 (you activate everything for the last 3 months). This was made more flexible by some user proposals, in order to avoid the exclusion of authors who don't normally power up. During this period, downvotes are not issued for not activating, but accounts are not supported either. Currently, the only way to not receive support is to have active power downs, and yet, there have been cases of support.

Before 2020, there was no culture of growth, as such; just the fact that to receive a vote from a whale, you had to delegate, and to delegate, you obviously had to grow (increase Steem Power), this was the support system before.

Here you can read one of the articles related to this point.
