I would assume that there is a good chance of a few 4chan members finding LW through MIRI, but a fairly small chance that a large enough number to cause problems will.
Linking to MIRI’s donation page might be useful but please please don’ link to LessWrong on 4chan—it could have some horrible consequences.

Ads have the potential to drive in a lot more traffic (especially in a negative way) than posts.
What’s the likelihood of 4chan finding LW by way of MIRI?
Around zero:

Someone on 4chan is likely to know of MIRI’s connection to LW, and point that out there.

A few members of 4chan that want to cause problems can encourage other members to go along with them.
