Topics marked as "Answered" by Moderators


Superuser
This is particularly happening when the topic is transferred from the "Ask a question" board to it's final relevant board.
I have found out Moderators do this "if the original poster hasn't marked it him/herself within some time and there is a plausible answer/solution in one of the comments" as "that topics with marked answers score better in online searches (SEO) therefore helping people with a similar question find an answer easier."
If you, as the originator of a question, feel that what has been marked as a solution is not, use the flag symbol

Thanks for reiterating this here and sharing your useful tip!
