One of the possible motives behind LJ's mass suspension was fear of losing advertisers. For those of you who would like to contact these advertisers regarding this issue, a list can be found here. My suggestion is this: let the advertisers know what happened, inform them that LJ hasn't followed through on the promise to restore all inappropriately suspended journals, and explain that you will not be patronizing any companies that advertise on Livejournal until those promises are kept and until measures are put into place to prevent this from happening again.
