As of now, the site has over 100 rejected migrations: questions that were migrated here and then closed. They are locked, so can be neither deleted nor answered, nor improved.
This is particularly unfortunate because some such questions come up in search results (this one has over 5000 views), damaging both the image of Web Apps and possibly its Google rank (as the visitors will immediately go back, seeing nothing useful here).
I think the site would be better off without most of rejected migrations, in particular unanswered one. Is there a better way to deal with them than going around flagging for mod attention?
