I've been seeing an increase in activity where answers are voted down without comment. I assume it's happening all over, but I only receive notifications when it happens on my own posts. A typical example is today when someone voted down my answer on sen-, mal-, and ne- which has stood for months with no concerns expressed.
If there is a concern about an answer given, an appropriate response would be to leave a short comment explaining what the concern is. That way people who come looking for answers can make an informed decision.
I suspect (but in no way know for sure) that this is being done by some newer members of the community who don't understand how Esperanto Stack Exchange is suposed to work. Is there any way to get this information out to users and encourage them to participate in the conversation rather than simply to vote an answer down if they don't like it or don't understand it?
