SCP Foundation

Also:
One of the SCP personnel "callers" accidentally calls Snakebite by his designation, SCP-XXXX-1, and while the radio signal goes quiet, the phone call log shows that Snakebite, without his lisp, asks how the caller knows his real name. Power shuts off for a moment to the offending building, and several breaches are attempted, but then halt as the signal returns.

The radio signal seems to ping from various SCP Sites eventually. This might be linked to the fact that 9 days after SCP personnel become the ONLY listeners, the show starts to change. No longer are they discussing races and cultures and histories that didn't happen in our observable world. Now they discuss SCP centric things.

The show adapts, and only ever centers on the realm that the listeners live in. Ex. If only children listened in, it would slowly become a show with jokes about boogers and cartoons and how mom and dad are the best (or worst, depending on the life of those who hear them).

The final containment procedure is to record the safer bits and slip them into actual radio shows, letting the DJs (who are the ONLY programming, 24/7) adapt to Earth norm, before letting it just be an hour long show, twice a day in the US and parts of Canada.

Firstly, Thank you so much for my first greenlight.

As for your concerns:
The Containment procedures would address them as -1 and -2 per usual, but then state "As of [DATE], -1 and -2 are to be referred to as "Snakebite" and "The Other Guy" within this document as to prevent a repeat of Event XXXX-xx, see Addendum Whatever-4. They somehow know what we refer to them as, also see interviews 9, 16, 122, 437, and 921" (Very loose idea draft, not actual wording I'd use)

The junior researcher who had caused the 'breach' (event?) was new to PROJECT LONG-TIME FIRST-TIME and made his first call IMMEDIATELY after reading the current procedures and had a brain fart bad enough to affect the whole operation. ("Yeah, I have a question for Four-Four-Ninety-Seven-One.. uhh.. shit. I meant.."
But, as it did lead to more information being gathered, and a possible final containment, he was only given a temporary dock in pay. The call would be logged with other calls, the post event interview with Junior Researcher might also be included.

But that's just one possible way of them (Us?) finding out that the Scip can 1) Affect the Foundation World (bad), and 2) Conforms to listener's reality (Useful). If it seems weak, that's fair. I'll get my gears turning on another way for that information to hit the reader/ characters.
