I did before I posted the link, and I didn't get redirected to eBay.
That link is currently still redirecting me to ebay.com.
I don't have a lj account and I'm not ebayed. Both Chrome and FF steadfastly refuses to steal my click.
Could have been a caching issue. The link is no longer broken for me.
Are you logged into LJ? Try logging out and clicking again.
Judging by some of the comments there, it was all done in Javascript. So whether it still happens to you or not, might be caused by whether you have that Javascript file in your browser cache.
