What kind of data? Most of them are going manual, if not already. A few of them are downvoting with their stake (returning value to the pool) and upvoting much more widely. I can't pull numbers for things (@abh12345), but in general, the stake is going much further.

The other thing to remember is that previously the buys on bidbots were paid to delegators in liquid, curation is paid in Steem Power. This is an important factor in my opinion.
