There's two kinds of text-based data that counter intelligence ops try to protect: Forum posts and 'fleet pings'.
For forum posts, an adversary can do exactly what you say - just take the meaning of the forum post and write a cable on it.
Fleet pings are how massive fleets are formed in EVE. Basically they are a @here ping on Discord, or a server announcement on XMPP or IRC. Fleet pings are important because if you know when your enemy is pinging for fleets, you know when and where to find their fleets to fight them.
For that reason, the value in fleet pings is very time sensitive, and cannot be transcribed by a spy in real time. Usually orgs will set up a "ping relay" channel for its top fleet commanders, with a bot that relays pings from enemy alliances. This is a very common interception point for obtaining watermarked pings and burning spies.
