I don’t remember LSOL getting in trouble (legally) with copywriting everything posted on the site, but it really pissed everyone off that they claimed ownership. Also, the brief period that they watermarked pictures so you could not post them elsewhere pissed everyone too… also, shrinking pictures so a bunch of text and advertising could be put on sides was gross… that was good riddance to bad rubbish.
Reading Bob’s terms of service, he does not claim ownership, but does indicate you need permission to copy / display / mirror things on this site elsewhere.
But if you ask the article author and he sends you his copy of the article, don’t see a problem.
