>>4He's referring to something from a long time ago, when someone was just spamming twitter links / random links constantly with the link in the subject, name, and post field and nothing else. It was happening often and the links were random half the time so I just started deleting them because it was spammy.
I don't think the "paste reddit links" has gotten to spam-levels yet, but I check every now and then and if gets out of hand I'm around, don't worry.
