Why would a poster have to "offer" people the "opportunity" to do what they are always free to do? Are posters supposed to wait for FReepers to send them "flag list subscription requests" ("Please, please, flag me, whenever you post something!") before the posters may flag anyone? I see that you have been a FReeper a long time, but if more FReepers shared your attitude, FR would have shut down years ago.
I disagree and in fact, I'd say that if everyone who posted suddenly ended up on a multitude of individual mailing lists and began receiving large numbers of "flags" from folks that then FR would have ceased to exist.
I am quite capable of reviewing Articles and Comments without assistance. I have no problem with flags addressed to one or two individuals on topics in which the recipient has expressed an interest, but I object to "spam" lists and feel that when someone puts me (or anyone else for that matter ) on a mailing list they ought to offer to delete them if requested.
It is just common coutesy.
