In order to ignore links when crawling in RSSEO! you will have to go to RSSEO! > Settings > Crawler. Here in the "Ignore links when crawling" section you can type the links that you wish to be skipped when crawling and also use wildcards in order to cover a wider range of URLs that should be ignored by the Crawler. You can use {??} to ignore 2 characters and {*} to ignore a variable number of characters.
For example in order to ignore the link:
index.php?option=com_rsform&ItemId=9999
you can use the following wildcard:
index.php?option=com_rs{????}&ItemId={*}
