+30 raptor... Oh man thats sexy.tbh just because someone has items like these doesn't mean they're a duper. Yes, some of them are certainly illegitimate but maybe they offered legit items to get them.
And to answer the upgrade question, items can be upgraded to +30 only. No higher. +21 is considered +10 and get the constant mega-bright glow for +10 items and higher but are also still able to be upgraded to a level just under what I guess would be the next upgrade level. (+30)
But now'a days...lots of people have +3 uniques...+9 items. Of course some of the items listed are really fucked up...cs+25 ...raptor+30, just impossible to be legit but some of them are just not as unbelievable to me.[/b]
That chitin shield almost made me piss myself <_<
