I've done this in the past for Cosmology@Home, which (at the time) would block all cores/threads of my CPU and not actually compute (really, Task Manager would report 0% CPU used, or near to it). Maybe that's been fixed, maybe it hasn't, but whatever.

I want to block Amicable Numbers because it posts a bazillion tasks that use all 36 CPUs (yeah, I'm rich, I can afford an i9 10980XE), and therefore blocks all other tasks (which isn't very amicable...) (sorry).

However, I don't want to block *other* mathematics projects, so I can't just block mathematics in general.

So how do I mark Amicable as "excluded"? (And how do I unmark Cosmology to see if they've fixed the problem?)

I have a similar issue with Rosetta@home whose tasks reset to "0% done" each time I stop and restart my computers, resulting in huge amount of wasted CPU time.
I just found a way to exclude it:
From User home page select "Scientific Porjects"
then select the project you want to exclude from the shown list.
The details page shows.
Look foor the last option. It is "Exclude"

Sorry about the delay getting back here. Yes, thanks, that was it. For some reason, I mis-read something and thought those were links to the projects rather than to the Science United settings for the projects. Ugh. Definitely a PEBKAC problem.
