The tag is not mandatory, but it helps us to find your post.
Also, note that we are voting STEM posts and not only science posts. History is thus fine, in contrast to what has been said :)
All I know is that steemstem voted for me quite often but not anymore and I haven't changed my style or something. Again, if I am doing something wrong I need to know so I can fix it.
To what I know, you have not done anything wrong. I would say: bad luck here.
Also, please remove the links. The distilled is not the place for people to self-advertise themselves. If you have a complaint, please go to our discord server (there is a room for that).
I have no complaints or questions anymore. I now know what's wrong. And I didn't post the links for self-advertise but to make a point. You are right...the problem is bad luck. I have it all my life following me ;-)
