Weird wording in our FAQ

This is completely minor, but it caught my eye in the signature section:

Please don’t use signatures or taglines in your posts, or they will be removed.

Maybe it's me, but the "or" feels redundant in there. It feels like "as", "because", . or ; would be better.

(Asking this here as opposed to meta, because it is about word choice)

Solution 1:

I think it's here worded as a simple warning, as a short form synonymous to “or else”:

or else
• used to warn what will happen if something is not carried out: you go along with this or else you're going to jail.

^{(New Oxford American Dictionary)}

Solution 2:

I actually agree that the second 'or' seems a bit awkward. As you said, I would say 'as' instead (indicating the consequence of the prohibited action), or a semicolon:

Please don’t use signatures or taglines in your posts; they will be removed.

Solution 3:

That wording is common usage, however I think it's awkward. Changing or to as would work well, or the or could be dropped entirely and the comma replaced with a semicolon.
