Twitter managed to unfollow over 47,000 of my follows in the space of three days, plus it deleted over 11,000 followers in 48 hours.

Trouble is, even if the followers are "restored" later, due to more technical incompetence you are not shown as following each other, and countless people will have unfollowed or autounfollowed in the meantine, if not actually blocked you for appearing to be rude. (Spammers often follow and unfollow when the follow is reciprocated.)

I found myself suddenly unable to follow on several occasions, despite being within my follow ratio by many thousands.

Even worse, Twitter put unauthorised blocks on people who were following me. I found that my account had blocked Stephen Fry and other long-term followers, for example, including some other VIPs.

The only way I could get President Obama's autofollow to work was by unfollowing blocking, unblocking and following his account all over again. It is not good to have to block people.

When I complained about Crystal's extreme incompetence, in an act of spite she removed my autofollow from the Twitter server immediately afterwards.

That is an example of malicious activity by a member of the Twitter staff. I wonder how many other acts of petty vandalism there have been?

Crystal often does not actually appear to read customers' emails properly, because on a number of occasions I have received messages from her which are generic 'copy and paste' responses, the content of which are irrelevant to what I was complaining about.

I've also know her to deliberately provide false information, ie lie.

She's not the only corrupt, incompetent loser at Twitter who should be fired - I would get rid of them all.
