Only accept #haiku tagged tweets if properly formatted.
Some tweets are discussions about #haiku and do not have the necessary cut markers (/) or (//), so they don't read as any form of poem.
ok. what about the “slahes only” radio button in the “my twyric” section at http://twyric.com/settings.htm ? Is this what you mean?
Some tweets marked as #haiku are more than 3 lines. Either there is a format problem or some people don't know what haiku are. Consider imposing strict 3 line structure on #haiku and similarly on #tanka (don't know it well ,but I gather it is 5 lines).
Also by being more strict about the poem format, you can minimise spam abuse, unless spammers start making spam haiku (see my comment about blocking those with links):
buy viagra / thick n hard / all night #haiku http://spam-r-us.biz
"slashes" you mean. That would be good; should also be a URL parameter. But originally I was thinking twyric should just ignore those poems claiming to be haiku or tanka that are not formatted in a manner suitable for display. They are probably conversations about haiku / tanka instead of an actual haiku or tanku poem.
