i don't see why they need to put where they got their info from, unless it's exclusive or if anything has been copied.. it's just like they've been told by someone.

'bla bla bla bla'
Source: My Mum told me at dinner

It's just the same as that really, so unless they copy something don't see the need for putting the source

and the spelling and grammar errors aren't really things that can be fixed, just gotta bare with it. they're only teens like all of us sooooo
