EJMR mod here. If PSR works anything like our site, then there's no way for mods to view the deleted posts. The deletion log only displays the last X deleted posts and threads, or else posts and threads deleted within the X hours, depending on the current settings.
If mods knew he relevant post IDs, then they could enter them manually into a special URL to restore them. However, post IDs are indexed across all threads, so mods would have to restore a large swath of unrelated posts in order to restore anything that might fall within this thread.
Mr. Singal might want to try emailing Kirk.* He has access to deleted posts in the database, even after a year, as we've seen on EJMR.
