New sites are said to benefit from an initial boost, but it is not measured
in years.

Google filed a patent that included analysis of registrar and domain
expiration. Whether they do anything with this controvertial discriminant
remains an unknown.

And conversely, spam content sites are registered em masse, for short periods
of time, and they vanish more quickly because there is little incentive in
maintaining them.

I concur with Cat. I can't see why change of registrar should indicate
something negative. Changes of a Web host likewise. A site often switches
locations and swaps 'affiliation' due to growth, which is a positive sign. A
recent example is wordpress.org. Being banned from a host is another matter,
which is possibly overwhelmed by the positive. You can check for the
'quality' of hosts and registrar based on their willingness to embrace or
harbour questionable sites. 'Bad neighbourhood' among hosts is almost
definitely frowned upon.
