West Coast coach Adam Simpson has expressed his anger after goalsneak Liam Ryan was targeted by another racist troll.
A user left a monkey emoji in the comments section after Ryan posted a picture of his three children.
It came after Melbourne's Neville Jetta also had someone leave a monkey emoji on one of his posts.
Ryan was forced to deal with vile racist comments last November on social media, and Simpson expressed his disappointment about the latest attacks.
"Everyone's angry, and annoyed ... but the best thing we can do is educate people about how it impacts their lives and their families," Simpson said.
"We're really proud to have the heritage that we do at our club, and having five (Indigenous) players play on the weekend - it's really good for us.
"We represent ourselves the best way we can on-field, but off-field, we've just got to keep educating people.
"It's not the first time, but it doesn't make it any easier. Our boys handle this quite often, so unfortunately, it's not rare.
"We're a very tight group. We've got his (Ryan's) back."
The latest trolling comes just days after Carlton veteran Eddie Betts opened up about the racism he has encountered throughout his AFL career.
Betts said he sets up emotional barriers every day when he leaves the house to brace himself for the racial abuse he may cop.
Former Collingwood and Melbourne defender Heritier Lumumba has openly spoken about how he was nicknamed 'chimp' during his time at the Magpies.
Collingwood have now opened up an investigation into racism at the club.
