Is this account "Tomte" another bot reposting years old URLs to farm karma? How common is this? Should this be allowed? What stops anyone else from running up hundreds of botted accounts all posting old stuff? By the way, he posted THIS EXACT LINK 9 times in the last 5 years [0]. Wtf is going on? I mean, if this isn't against TOS I guess I should do it too so since I gain 1 karma point for every posted story.
