If I publicize a “request address” with the intention of allowing people to support my online efforts, am I risking my privacy? i.e. if many people send me Bitcoin via that address, ostensibly that leaves a visible chain of money going into that “account” (for lack of a better word).

Even if I immediately transfer money from that “request address” into my main wallet address, there is still going to be a money trail, no?

What can be done to mitigate that? Should I change the address every time someone sends me money, or perhaps every week or month?

As a for-instance, ThePirateBay has a Bitcoin address on their main page; it looks like they’ve received 12.3 Bitcoins via that address.
