Yes it's bait but also there is real science behind it. Sun spots are magnetic knots that are wound up magnetic lines. If the lines snap they could pull huge amounts of charged particles and launch them at earth.

The risk is that if big enough it could strip back the our magnetic field reducing our production from radiation and all the electrical charged particles. This could mean electrical systems are disrupted, destroyed, or even catch fire. In the worst case the amount of radiation could kill millions.

So yeah chances are very low but never 0.
