Is it worth trying to report a competitors PBN to G and try and get them slapped with a manual action? I've got two cases where I could do this and make some significant financial gains from it. I know it's a pretty asshole move and I'm willing to accept that. One case is a local SEO opportunity. The top competitor is a national brand but from my research they are ranking based on a few spammy backlinks purchased 4 years ago and they haven't done anything since. It's very easy to discover their backlinks and very easy to tell they are paid for and spammy. My plan there is create a PBN and spend time to rank a business I have connection to and when they start ranking then report the top competitor to G and try get them slapped. Only problem is I think they'd try and come back stronger. They have a decent amount of money but killing their rankings would definitely scare them. The other is a PBN I uncovered while doing keyword research. I found a low comp keyword with 20k searches per month with affiliate sales opportunities as well as adsense recommended bid of $6, Companies are paying for adwords quite competitively. The guy ranking number 1 is ranking solely off an 10 site PBN which is obvious as hell. All his expired domains are not niche related and he's used the same theme + spun content on all of them. It's blindingly obvious. Plus all his expired domains are only DA15 ish. It's pretty weak sauce and I have a tonne of DA27/DA28 expired domains that I could do a lot better with. I estimate he's making around $300 ~ $400 a month off this site, so it's well worth it for me to consider building a far higher quality PBN then trying to kill him by reporting him to G. I try to go for highest quality that would pass a manual review. Is it too much of a dick move? I believe in being ruthless to win. Interested in the communities input.
