@Daniil, as far as I remember I have added that message to all I have handled, (which means I agree with you.) I do not know what the other mods do.

I am now working on the current batch.

But maybe skip the closed or duplicate ones when you do such a series.

I have not added it to one of the Q, because it was closed (I think as a duplicate.)

We leave them, they warn that the answers will likely be no longer valid, as they were for that short time, with special conditions.

@Daniil done but please smaller batches next time. One did not want to work as it had an other notice on.
