AW: OT: On-Rev antispam (& reCAPTCHA)

[Tiemo Hollmann TB]

Hi Björnke,

the business with email harvesting and nasty links are of those business
models I know. But just entering a stupid (probably not working) email
address into my newsletter database or entering senseless entries (without
links) in blogs or guest books - I can't see any sense. Are these
"collateral damages" of their bots or do you see any model of value they
take out of these entries?
