Twitter is looking into it? Wow. I'm overwhelmed.

I've been at several conferences recently at which Twitter was being used as a live back-channel for the presentations. Obvious spam-bots flooded the hashtags so we turned it off. Now, I don't even bother :(

Seriously, what sort of sample size does Twitter need to develop some algorithms?

I had a couple of disastrous experiences with Bluehost, including having accounts suspended for generic ToS violation without notification and SSH access suspended because they'd changed their policies. They now require a copy of some photo identification, which is fine, but they didn't notify me and simply disabled access. Not good when sites are being published and backed up via rsync.

I've since discovered that even after I'd closed my account with them, they kept my personal and domain details despite being expressly instructed to remove them.

It depends on how much privacy and reliability mean to you, I guess.
