It’s nice to add a Twitter RSS feed about a place to your site as it will generate plenty of fresh content and pick up things you might not know about. But there is a danger that spam will end up appearing.
You can minimise this a little by using Twitter advanced search and cutting out some common bad words, for example for Stoke I exclude ‘porn’, ‘sex’ and ‘escort’. Then you can use the orange link to copy the RSS feed (example) into a WordPress widget.
That will cut out quite a lot of spam, but you might still want to warn your readers that you are drawing the feed in from a public RSS feed and they should follow links with caution.
