I have found over the years that it is a good and safe thing to rely on our instincts and whenever a thing sounds too good to be true it often is.
Having said that I also think that there are times when we have to be a bit brave if we are to find as many of the benefits that are out there that we might need and can use.
Sadly once we are registered to anything new to us on the internet and have given contact addresses or numbers it can often happen that these "marketeers" will use this information to make money out of us or bombard us with stuff that we neither want or need.
Just another of the traps on the internet I am afraid !
Then again if we quickly find that a certain website or company are targetting us we can register with the Telephone Preference Service ( TPS ) and/or the Mail Preference Service ( MPS ) and block this address from our e-mail client. ( Of course if these entities are foreign ones this might not always work ! ).
But, then again, as my old Irish grannie once said: "Faint heart never won fair lady !"
