It’s caught me out on more than one occasion and to this day I still haven’t figured out how to ‘unblock’ a user.
Dear Twitter, please fix! In fact, I’ll do the work & give it to you for free, just stick this line into your CSS, you don’t even have to touch your HTML as it’s already being referenced!!!
The update:
#follow-requests .follow-request .right-box .block-link { padding:12px;}
#follow-requests .follow-request .right-box .block-link:link, #follow-requests .follow-request .right-box .block-link:active, #follow-requests .follow-request .right-box .block-link:visited { color:red; text-decoration:none;}
#follow-requests .follow-request .right-box .block-link:hover { color:red; text-decoration:underline;}
*zen*
It’s pretty annoying – I’ve done it a couple of times too. Hopefully they fix it at some stage.
Re: blocking/unblocking people – you can do that on each person’s profile page. On the bottom of the right-hand nav pane, there will be a grey “unblock” link (it’s “block” if you haven’t blocked that person). http://help.twitter.com/forums/10711/entries/15355
