Is toplowridersites.com Safe?

This site has come to my notice through referrer spamming on one of my sites. Any site that indulges in referrer spamming is a disreputable and unscrupulous one, and NOT to be trusted, as it most likely has other, more troublesome issues. Later note: Actually this site hotlinks to an image of mine of a supposed Reiki 'Master' certificate, which I display at all only to make the point of how bogus ALL Reiki 'Master' certificates are, and presents it in a gallery of "Free Printable Reiki Certificates", which is disreputable behaviour, both in the hotlinking (image theft by any other name) and in providing any service that purports (I think in this case incorrectly, i.e., dishonestly) to provide Reiki certificates that people could forge or otherwise misuse to present themselves as supposedly qualified practitioners or teachers without the training and practice that would make them supposedly so.
