Well recordings have to be forgotten as well otherwise the moon landing plot wouldn't have worked.

Haha... and speaking of going back to look for the Silents in the last season... look what we get if we go a little further back again:

Looks like Ark in Space is also a favourite of Moffat's:

how can that somebody know, since that somebody would also forget? I mean, its a great idea - dont get me wrong, love the concept - its just too good a defence though. I mean, prisoner zero and the rest should also have forgotton about them (or never have been told in the first place)

It seems like the Silents can only manipulate an observer's memory of the portion of time between making and breaking eye-contact with them. They can't erase your memory of a time when you weren't looking at them, or at least there hasn't been any evidence of it so far.

So, if an observer, before breaking eye contact, was to pass on their first-hand information about the Silents ("argh, it's an alien!") to a second person who isn't looking at any Silents, the second-hand information ("that guy's screaming about an alien for some reason") can be retained. We actually saw this during the picnic in The Impossible Astronaut - Rory was curious about what Amy was so horrified by.

Using that kind of scenario, it would be possible to figure out more and more scraps of information about the Silents, until you can eventually come up with the note-taking strategy they devised in Day of The Moon.
