I doubt very many people that would fall into the category of a sleeping whale or even dolphin have their auto votes set up through one of the services you mentioned. Much more likely to be a vote bot they set up, particularly if (as you suggest) they were active early on the platform before these services even existed!

Incidentally, I can tell you from experience with Streemian that my auto votes would stop working every few weeks in any case and I would have to go and re-enable them - so just kind of out of sheer crappiness of the platform there is already something like what you suggest in practice LOL
