SCP Foundation

I wanted to run this idea by someone. It's a dictionary that's constantly changing, and it makes you perceive what you read about as the opposite of what it is.
What if a week or so after the Foundation acquired it, a definition appears for "SCP Foundation", hinting that it is sentient and wants to be free?

• What if it's in a language that a reader doesn't understand?
• What if someone reads a definition of "paradox" or "lie" or "falsehood"?
• Why does this merit special containment and not getting chucked in regular anomalous item storage?
• How would someone discover the effects? (How often do people read dictionaries for more than a few words at a time?)
