A lot of people don't give this card any love, but I have always found it useful as a "surprise". Don't drop it out just for funsies to get the -2 STR necessarily...drop it when you've already parasited a big piece of ICE & the corp thought they had a turn or two more to purge. Even if you get it late, it can still be useful...unlike what can happen to Hacktivist Meeting. Look at it kind of like a Surge that can stick around to be relevant.

I feel like this is the key. Realising that stuff is safe is something corps do. Then Scrubbed comes down and ruins your day and your Tollbooth! —
Wonderful review, and a good idea. Being able to instantly "surprise" Parasite something, or bring something to Darwin radius, is potentially huge. You can bait them into committing to a scoring window that doesn't exist. —
And with the release of D&D, a new combo can be had! Scrubbed + Prey to reduce the number of cards you have to discard by up to 2! —
