Blackmail email threatening spammy back links - coming from store contact form

Hi,

Has anyone else received an email/emails from their store contact form threatening to inundate with spammy backlinks, to destroy google ranking - see attached pdf.
Has anyone any advice on how to handle this, or how to find out the origin of the emails from the store contact form.

This threat has been carried out - though it seems to pre-date the emails. We have had 10,000s of inappropriate links(see attached screenshots) and though this is only recent we have dropped from near the top of the first google page to half way done the second page.

This is very concerning and difficult to address, as google have no interest in helping us, and we are actively trying to disavow these files.

If anyone has any advice on how to handle this attack please help. You will all understand how demoralising it is to work so hard on something to see it attacked in this way and to have such limited options to redress the problem, we are actively trying to disavow these links.

Any advice would be much appreciated. If anyone has knowledge or experience of this could they let me know how they handled it and if they were able to fix their google ranking?

I have this too!!??! email arrived today, so you are saying that this is a real threat to my site?

If you’ve received a blackmail email threatening to spam your website with links, it’s likely coming from a store contact form. Spammers often use these store contact forms to collect email addresses and send out spam messages. To protect yourself from this type of spam, you can either disable the store contact form or use a spam filter to block messages from the email address sending the blackmail email. If you need further help, I recommend contacting the experts from www.digitalforensics.com. They will help you easily!

I also want to avoid the spammy back links that are coming from the contact form of store. I don’t want to see the attached docs or pdf due to my site performance and safety.
