LLDS Energy Regulator lets you prevent the trash for 3. With multiple Acacia out and lots of virus token generation, this can get out of hand very quickly.
Regardless, you need to have an outlet for the money you make. Gaining 6 for them purging your Aumakua doesn't help much if that's your only way in. However, pair it with other virus counter generation and classic breakers like Paperclip/Black Orchestra/MKUltra and you can use the credits to rebuild your counter pool (probably by making successful runs), making the purge moot, or at least buy you enough credits to breach their remote while you build them up some other way.
