It’s not that you’re an idiot, but it’s wise to avoid using a chromium/blink based browser since they are building a dangerous monopoly. Firefox is the best known alternative, but there are a couple other options.

Be careful about “unsubscribing” to various services.

They will unsubscribe you, but then they also have all of your information (name, address, anything else) on record and confirmed. They can profit when the sell that data to another mailer “service”. It’s like a Hydra.

Is there another source reporting that?

Edit: this is probably a side effect of federation, but at least four people have confirmed it’s most likely a gas leak.
