I'm talking about questions that are duplicates from word to word, not even reworded one bit.

For example:

DLOGTIME complexity class and testing the length of the input string

In general, exact (word-for-word) duplicates should be deleted, yes. However this case is special.

2018 is a crossposted version from math.SE, migrated here, then closed and merged into 2011.

We should not delete those because it would break the migration for math.SE (the whole forwarding thing from link to the math.SE version). This is due to a bug. See the corresponding meta discussion; hopefully this will be fixed soon.
