Dark Deities

We don’t know what the Voice said to Spamton on the phone, nor what they did —if anything— to make him successful. We could speculate several things:

The Voice could have been giving Spamton instructions or was acting as an intermediary so that he could influence the Light World. If the latter, Spamton making a deal with Tenna was part of the plan, as it would be the next step: from spam, to print advertising, to television…

If Spamton was changing media to better advertise and capture the attention of the Lightners, was his main goal to become more and more "real" then? Is his face on a magazine?

However, if he had received instructions, was his presence on TV World still part of the plan? And, most importantly, what was he supposed to do? Unlike in the Digital World, he had a deadline to act — Kris would have to return the laptop sooner or later.

Now, considering the deadline, what scared him? Being told that the deal was off —mind you, he got a second call before getting evicted from Queen’s Mansion— or that the time was up? If the poster in the Z-rank room is anything to go by, Spamton was having a good time with Tenna; perhaps he got too distracted and the Voice simply reminded him.

Or, third option, what if what horrified him was what he had been told to do? What if the problem wasn’t that he wasn’t allowed to share his secrets, but that the secrets were too harrowing to share?

Dunno about you guys, but I don’t think Tenna would have taken “to become Big Shots, we gotta kill Kris (and/or Asriel/Toriel/Asgore)” very well. And also, I don’t think Spamton would be down with murder at his best either. Even at his worst, trying to steal Kris’s soul was a last resort, one he only used when the NEO suit and the crystal weren’t enough.

It’s, however, the reason Spamton could resent the TV so much — especially if he felt his feelings were one-sided: sentimentality made him hesitate and then, he had lost everything.

The Voice made no further calls —the one from the Digital World being the exception, maybe to warn him of the machine’s existence in the basement— because Spamton had already been told everything he needed to become Big Shot.
