Twitter, Facebook... Why do you think they would like the dummy accounts removed? As long as they are not overdoing it, they bump the statistics. I know personally people that run hundreds of thousands accounts on Facebook for marketing etc, yet they say FB does very little difficulties to them as long as they stick to some limits in posting, sharing and liking.

Unfortunately reaching 1 Billion users while closing one eye on bots is very tempting.

Astroturfers need to have their internet privileges permanently revoked.

because if it's blatant, they may be liable.

As long as they will show "we have deleted 100K bot accounts a day since a year" they wont. No one will blame them for not inventing "foolproof" or workable spam filter, even if it is for small team of security engineers. All they need is some number of abusive accounts to ban, so statistics are right.
