That's a bad mentality, sorry don't mean to be personal but you cannot judge someone based on their signature and its payment.
I judge people based on what they post and then I see their signature (sometimes, not always) so I don't know how you judge before reading. But I can't blame you either because most of the low-paying campaigns are hiring shit posters.

The guy represents ChipMixer, one of the highest paying campaigns and he doesn't even write in English that one would classify as a secondary language, let alone native.
NOTE: Make no mistake, I never judge people based on English because it's a language not the measure of one's ability. But to put things into perspective, not everyone from a top signature campaign represents quality.
