not had a prolific survey now in over a week  -very disappointed but I supposed this happens.

I was reading the Prolific blog which does provide a clue as to why this happens. Basically they seem to offer more surveys to more "naive" (in the sense of not so experienced at taking surveys) people who haven't been active at completing surveys recently.
https://blog.prolific.co/data-quality-at-prolific-part-2-naivety-and-engagement/

"When it comes to distributing studies evenly, our primary tool is something called adaptive rate limiting. In essence, when the number of active participants is high relative to the number of study places available, we give priority access to participants who've spent less time taking studies recently. When studies are filling particularly slowly, we then loosen the limits and let our more 'prolific' 😜 survey takers work their magic.

This mechanism gives us several parameters we can tweak in order to distribute studies more fairly and restrict the number of "professional survey takers" on the platform. By increasing the limit, we reduce the rate at which a participant becomes non-naive, but the catch is that this accordingly slows down data collection."
