That only happens when:
  - you have newszilla6.xs4all.nl closeby and people use it heavily
  - some stupid ISP has a 'customer' that is sending broken 6to4
    packets to ddos somebody of the internet and even though the ISP in 
question gets contacted simply ignores it as "you buy more bandwidth".

But it is good that you actually consider this point, running an 
underpowered/undermanaged relay can cause real issues.

But remember that there simply is not a lot of IPv6 traffic at all:

As such, not too much to worry about, though traffic is getting more and 
more over time fortunately.
