Honestly??
I would check them out very carefully. Be suspicious.
I followed the link to
Forever - The Company - Consumer Interests . The page feels wrong to me. It claims membership of all sorts of organisations. Just one example, there is a logo for the dsa (it is normal for the logo to contain a link to the organisation - strangely, on this page, there is no link). On this website, I can find no contact information - phone numbers, address, emails, nothing. The recruiting page (that you provided a link to) also contains no contact information beyond a mobile number (no landline??) and no geographic address.
The company that belongs to the DSA (see
Direct Selling Association UK, DSA, for Companies, Customers, Consumers. ) is "Forever Living Products (UK) Ltd", whose website is shown as
http://www.foreverliving.com/ - it is a completely different domain. The domain is also owned by different people (you can do a WHOIS on the two domain names).
Probably I am being neurotic and the scheme is genuine. But before I put my money in, I would follow up all the claimed memberships, DSA, OFT, IIP and the other 5 that I don't recognise, and making sure to note any small differences in names. Scams work by being convincing. One scam copied the BBC site!
Try speaking to the parent company, see if they have heard of these people. Contact the OFT and IIP and see if they have heard of these people.
I really hope I am being overcautious, but I would hate for anyone to be caught in a scam. Good luck.
