No. If people did that to me I'd get hundreds of emails. Would you like every online user to notify you when they link to your material? I know some of my articles get linked via the "Link Suggestion Tool" on Hubpages and others get put in tons of forums.
With the tracker in there you net 9-12% of views you direct to them and they get extra traffic. And if they get a lot of traffic they're unlikely to notice or care anyway.
If it's a really niche topic you can leave a comment on the hub letting them know you've written along a similar vein and linked to them, but this isn't mandatory.
