So, in essence, TMDA's unfortunate creep in popularity is extremely harmful because it threatens to very quickly double or triple the damage spam causes. > Plenty of people on these lists have admitted to, and in fact encourage, > ignoring challenges.

I'm wondering if there's any good resources on the web that summarize the harms of TMDA, and if so, where they are located.
