As manager of @de-stem, I want to state that we did not support over 800 unique authors on our own. The high number of votes casted by @de-stem is a result of our account trailing the @steemstem vote. To have a more accuratly picture of our work, you should rather count 100% upvotes from @de-stem, as they are exclusivly going to german STEM posts before steemstem is voting. Also, we have a weekly-fortnightly report of our activity where you could look up the info too.
