New Customer spammy markup warning

[bendh]

I just won a new customer, yippie. Bad news after i got the full story it seems they have a google penalty against them. It could be an old malicious employee with back links.

The error in GSC is spammy markup, would anyone else care to take a quick look and see what the  main issues are, im not sure of the tags or all the additional info and alternate names, they are relevant but maybe too much in rich snippets.

the site is aipctshop.com.

Thank you in advance.
