It's likely that your particular unsubscribe link has become public, perhaps by being posted on a blog or social networking site, and someone or something (such as a web crawler) is repeatedly following it and triggering unsubscribe emails to yourself.

Ah yes, the filters match against the item title alone, rather than the generated "{feed_title}: {item_title}" email subject string.  Another one to add to the help text clarification task I think!

We're looking into using regular expressions for the next iteration of filters, which would allow string start/end anchors along with all manner of powerful string matching.  And no worries :)

The filters will do a case insensitive match with whatever string you provide - but it's reasonably naive at present, so if trying to phrase match things like double spaces, line breaks, HTML markup etc. could cause a miss.

Can you drop me the feed URL so I can test against it?

The password shouldn't be required - can you clear your browser cache, retest and see how you get on?  If it continues, drop me a mail at info@blogtrottr.com and I'll have a look into it for you - perhaps it's something specific to your account.

Hi, yes, a refresh of many of the words is needed I think!

Actually yes you can - if you add a input named schedule_type to the form and give it one of the following values:

0 - Realtime
1 - 2 hourly digest
2 - 4 hourly digest
3 - 6 hourly digest
4 - 8 hourly digest
5 - 12 hourly digest
6 - Daily digest

e.g.
<input type="hidden" name="schedule_type" value="1" />

Or you could present them as a <select> list.

I'll get this written up properly and added to the Help page.

I'm very sorry about this, but it appears that we're running into Yahoo's rate limiters - they won't let us look at more than a certain number of Pipes feeds per hour, and the Blogtrottr/Pipes combination has become rather popular.

We've been trying to talk to Yahoo about getting whitelisted for the last couple of months, but have been unable to get a reply from them.

Have another try in 24 hours time, hopefully things will be a little calmer then.

We have some thousands of working subscriptions to Pipes feeds - indeed so many that we're beginning to fall foul of Yahoo's rate limiting.  Which might be what you're experiencing here.

If you can email the feed URL to me at info@blogtrottr.com I'll have a look into it for you.

Agreed.  Navigation has had a tweak recently, so it should be a little more intuitive now.

There is now a 'show contents in digest emails' option in your Account Settings that enables just that!
