no it will effect the USERS of bid bots, who currently vote at 0 minutes on their post and get a big chunk of the curation reward from the bid bot. Now, any early voting behavior on posts that receive bid bot votes will send some of that back to the pool. Ultimately, that may trickle down (or up) to the bid bot operators themselves, but only if it has an impact on how many users are using bid bots. If users keep buying the votes even if they lose money (and that is already the case often, and people still do it) then it won't really have a huge impact on the bid bot operators. But it will return some money to the pool that would otherwise have gone to posting that was only receiving high payout because of bid bots.
