Earlier quoted context omitted.
gp used "rent seeking" correctly. The concept of "landlords do nothing while collecting passive income, therefore not creating any value but instead are just exploiting that they own the land" would be correctly described as "rent-seeking behavior".
You should read the wiki article. Criticising landlords is fine, but words (and phrases) have actual meanings, and the term "rent seeking" has literally no place in a discussion about landlords.

Having "literally no place" is certainly a strong choice of words, particularity as it was introduced in this thread as being a inaccurate label to apply to landlords.
Personally, I first learned about the term applying it to Feudalism, in which the (land)lords' only contribution was their ownership of the land. That example alone seems to pretty handily disprove your claim of "literally no place", in fact it's specifically cited in the Wikipedia article as the Georgist interpretation of economic rent.
