Forum:X360A.org = reliable source?

With many people adding X360A.org as a source to achievements in incoming games and DLCs (at least we should be grateful for them making the effort to provide source, ends justify the means), I wonder if that is a reliable source.

Many users and admins are removing achievements of which only source is x360a (for example, in MW3's or the Rezurrection achievements' articles). For that, I ask if it is really reliable, because as far as I know, the achievements aren't addable/editable by everyone, and the only bump that comes on the way is the uncertainty of are the achievements leaked. If that's the case, it shouldn't be more unclear what to do.

On a side note, if my grammar or text setting is bad, don't mind it. I'm not feeling the best, but I wanted to get this on the air. 20:01, September 26, 2011 (UTC)
