Any ill effects if the crawler is removed?

Yup, asking today instead of sharing. Ever have your SharePoint domain crawler account show up in every @$%!%!&*!@ list where there's a user lookup. I seem to have them in any of the sites we have spun up around here. A freaky looking account name that nobody seems to know who it is (ours is called spsSpider).

So the question is, are there any ill effects removing the name from the profiles? I mean, the account is setup in the Central Admin and part of the admin group so it should have access. I guess when it "visits" the site to crawl it, it leaves its name droppings there just like any user but is there any problem removing the accounts profile from the SharePoint Profile Database. Does it come back when the next crawl happens? Is there any way to get rid of it so your users don't see it or maybe I should rename the account to Alan Smithee (heavy thud as nobody gets that joke)?
