I am sure that if there are any networks who are filtering you, be
they ISPs or end-users, such that you can't reach something through
them that you'd like to, a small payment will almost certainly cause
an exception to be installed in whatever access list is being used
to keep your long prefix from occupying a "slot" that could be occupied
by a longer prefix or something otherwise statistically more likely
to be interesting to their customers (or themselves) than your /24.
how well do you think this scales? if the isp(s) you are asking think of
it as what could be the first of a few thousand such requests, do you think
'small' payment might be a bit optimistic?
