spam – Backlink Blackmail scam – what to make of it?

I received an email through a clients web form, and – while I have no intention of complying, I am not sure what to make of it. Does anyone have any insights into this kind of spam? I’m curious because it seems to be targeting people with SEO knowledge, but surely those people will have the knowledge to check and disavow the backlinks? Are they trying to boost DOMAINTHEYWANT.TOPROMOTE (not the actual domain). Relatedly, even if you do comply they promise to “reward” you with a backling from a site which would be detrimental!

I do note that DOMAINTHEYWANT.TOPROMOTE and my clients website are entirely unrelated. The DOMAINTHEYWANTTO.PROMOTE does appear to be a crappy site in Japan which deals with money/loans (in both English and Japanese)

The email was as follows (it was a web form, so no meaningful header). For what little its worth the website log shows –

Good Morning

I am the PR manager for DOMAINTHEYWANT.TOPROMOTE which cover bank
loans and is a profitable affiliate site based in Japan.

I am currently running a PR campaign for my client and I would like to
request you to share our website DOMAINTHEYWANT.TOPROMOTE on your
social media, bookmark it and give us a backlink on your blog
MYCLIENTS.DOMAIN

I will check in a few days’ time and if I do not see a backlink to our
site and social signals, I will spam MYCLIENTS.DOMAIN with a whole
load of toxic link farms that will inevitably drag your site down the
rankings.

Just to show you that I am dead serious, please take a look at the
backlink profile of this url and note all the spam links being created
24/7. The same destiny awaits your site:

Please do not try to report me or try any monkey business as this will
only piss me off and increase the severity of spam going to
MYCLIENTS.DOMAIN Should you comply, I will reward you with a link on
our site.

Thanks in advance.

Kind regards

John Dignum PR manager for dimepiecedesigns.com
