Considering that J. F. Queeny[1] founded Monsanto, that seems like a strange choice for a covert shill account. While I don't read much about other issues you may be referring to, being a farmer[2], I end up coming across the GMO and pesticide topic fairly often and I've noticed it tends to attract a lot of misinformation about agriculture. I expect, in many cases, these accounts follow these interest groups because they are easy targets to make fun of. Bullies perhaps, but unsurprisingly the internet has them just like the real world.
