My wife's previous number was one that apparently belonged to someone else at one time or another. Every Thursday thru Saturday she would get texts from a club in Houston advertising who the DJ was for that weekend.

For a long time we ignored it. There were only three or four texts per night and lonely one weekends. One night something went berserk with the system. Over a period of about four hours we got enough texts that it amounted to about $25.00. Given our rate plan at the time that must have equated to about 100 texts. None had a way to opt out.
