There seems to be an error in the spam.txt file, that flags people that use double greater than signs to point to other posts as spammers, I traced it to a line in the spam.txt file where those symbols are located (ampersand greater than comma ampersand greater than comma)
Would recommend fixing this, it was hard for me to find and seems to possibly affect everyone that uses the spam.txt file and doesn't know that is a problem.

(sorry for the weird formatting of the post, but due to the presence of the error in the spam file, I can't submit my post with the example typed as it is in the file.)
