I received well over 1000 SMS messages in 2020 from the Biden campaign. Replying 'STOP' worked... for that one number but since they were using a huge army of volunteers to SMS out messages, asking them to stop was pointless as there was a seemingly endless number of others sending out messages. Legal or not, it wasn't ethical. It only started after I updated my voter registration because I moved between counties. The online form had telephone number as a mandatory field but I didn't realize that would be released to political campaigns.

Trump and Biden both spammed my physical mailbox with the usual slick mailers, though the Biden campaign had an interesting twist in that I kept getting what appeared to be hand written postcards from people in metro Atlanta where I lived but every single one of those post cards was postmarked San Francisco. I'm giving them the benefit of the doubt and think maybe the postcards were written in bulk by the actual people in the Atlanta area and then sent to some Biden associated organization in SF, who then paid the postage for all the individual postcards to go out.
