Not similar enough to be mistaken for each other, I believe. Even a beginner who knows at least a bit would notice the clear lack of mirror patch, very visibly present amongst the most commonly kept species of the Grammostola genus, G.pulchripes included.You haven't burst anyone's bubble because that is an LP. They look very similar though so I don't blame you for the confusion.
Where did I misinform anyone? I said the same thing as you before you even posted it. And yes your right its not a Grammostola.If you lack knowledge about the subject, then it'd be advisable not to try to give advice at all. No information is better than, though given in good faith, misinformation.
