Used for when any Nicoseiga post or picture are no longer publicly available. Starting October 30th 2024, Nicoseiga has blocked all access from outside of Japan.
Some links of the type "source:*lohas.nicoseiga*" also return 404 even though the file might still be available somewhere - see an explanation on github at issue #4496 under the "Store the right source" part.
