Is ukinvestmentguides.co.uk Safe?

Website advertised by unsolicited email. Unsolicited emails advertising this site claim to offer a "fantastic ... investment opportunity". The homepage of the site contains nothing but a 'coming soon' page., but links in the mail point to a subpage of the site which claims a 'typical return on investment' of 18-25% and includes a sign-up form where visitors can enter their contact details for more information. Spam-advertised "investment opportunities" are typically deceptive, and there are a great many additional warning signs in this case: the use of a hidden sign-up page, and the claims of implausibly high returns. This may also be related to previous very similar spam runs, which used different domains and offered similar 'opportunities'. Text on the website appears to have been written either by a non-native English speaker, or by a program. For example, "Share market is one of the most preferred or most hated companies depends on their condition. The spirit of the crowd rising market is characterized by the build-up. Index continues to rise, the 15 days will be interested in buying this sudden spurt." is near-nonsense that can only have been either generated automatically from a text corpus using statistical methods, or by machine translation from a non-English source. The fact that they put gibberish like this on their front page does not inspire confidence. Positive reviews of this site on MyWoT appear to have been written by the site owners, who are apparently no better at astroturfing than they are at anything else. It is highly likely that this is a scam or that, at best, the claimed returns are extremely exaggerated.
