Ihub is set up to detect the mere mention of investors hangout. The way to circumvent their system is to not mention hangout at all, just that they should visit a link.
Instead of copy pasting hangout into iHub, you need to disguise it. Go to tiny url: http://tinyurl.com/ and copy paste a link into their converter and it will spit out another link.
Take a look at this link right here: http://tinyurl.com/8mkmltb
It is a link to this TECO board but it has been disguised by tiny url and now it is not only a shorter link, but it won't get picked up by iHub's systems. You can actually give that link out on iHub or make your own using the process I described.
