What do you mean 1234?

You had a number for your deckname.
They show when you build "openly"
Open builders are usually part of the trolls in here, because when there were more people in here it was a constant bother.
You see trolls would often post unfinished decks to lure people into commenting on it.
It also has a second use, sending messages.

Ah, I add all the cards to the deck before I add a deck name, didn't know it had numbers as place holders.

It does. 8 ciphers or so.

Trolls constantly send messages, and there was the odd chance that you were a troll sending a message.

The "message" as I saw it, was the location of a trolls nest as well as an empty location.

They use views as a way to store interesting spam and personal decks.
It's a neat backup system.

If you use the search engine to find decks containing exactly 1234 views you will be able to see what a nest looks like. Just don't look at too many of the decks, as this will ruin their neat collection.

The trolls got an automated viewer, probably a homemade program that clicks and move the mouse to generate the number of views they want.

A few others have spotted "odd view counts" and I'm writing a post about it for my conspiracy collection.

Wow I had no idea any of that was a thing. Here I am just trying to add my paper decks onto the vault to see their value and make quick changes lol

Use several sites to check on prices.
Price manipulation via sites isn't impossible, so just to be on the safe side...

Here's a list of odd stuff on mtgvault and other sites

By the way, the view nest is by far the most fragile, because anyone becoming aware of a highly used view "number" become curious and view a few, ruining the thing.
They got much more solid nests in other searches.

Sometimes you just have to search for a key phrase to find them.
When I accidentally stumbled on deckname: std
The trolls stopped using it, waiting until I've forgotten about it.
