I have a Cali State Tax Lien, and I just GW'd the LA County Recorder's Office. Although I also stated that they have been reporting the information as incorrect for the past two years and have violated my civil rights under the FCRA, because the amount listed that I owe is incorrect (they say $1173, whereas I know the back taxes were for only $483, and I have proof of that).
I'm waiting to see what happens. The LA County Recorder abdicated her post recently, so I don't know who is going to read my letter and make a judgment call.
Liens are hard to get off, but I don't think it's impossible. Nothing is.
