There seems to be a systematic campaign of closing question just because the OP did not accept one of the answers
Example 1:
I’m voting to close this question because it seems that OP is not active anymore and consequently (s)he will not accept any of received answers.
The question seems clear, does have a MWE, got multiple answers and the OP gave feedback in a comment with thanks and acknowledging that the solution worked.
(the question was reopened in the mean time)
Example 2:
I’m voting to close this question because OP after one and half year still not respond to comment nor to received answers.
The question might not have a MWE but looks reasonable clear and shows some code. The question received multiple good answers. The OP posted feedback and follow up questions from a new account as a (non-)answer, so maybe simply has no longer access to the old account.
(the question was reopened in the mean time)
Should the time and effort the of the users writing answers be valued and the information be preserved for future users regardless of some green tick being clicked or not?
(I'm not providing links, because I don't want to call out a user. I'll put them in a deleted answer for trusted users to see)
The person writing the answer can be [...] a third person, that may or may not use the Community Wiki feature.
very interesting - I did not think about that! And I immediately practiced it (tex.stackexchange.com/questions/344656).
