I once featured in a fairly big one. Luckily the crew were not at fault but its never once got in the way of finding work. In fact I think that in the UK only the AAIB and employers involved know who has been in a smack, the CAA ask on your medical if you've had one in the last 6 months, but
AFAIK they keep no records. The media only tend to know if you're dead or a hero.
Now prosecutions or cautions, the CAA has a VERY long memory on those as one of our pilots found out.................
