'The & to & conversion is another sign of a poor quality crawler.'

I wasn't referring to any of them but to '&amp'. Important difference. Also explaining my failure to filter it from parameters since parameters contains an equal sign. E.g. ...&amp= something or even &amp=

& or & would also easy do filter out. But that is not the problem I'm having here. It's different, hence my request for assistance to the nginx community.
