There are various potential factors affecting this issue and as such the maximum length that the filter settings can accept without breaking the plugin can differ between users. Unfortunately, this may be an issue that requires rewriting major portions of the TouchPortalAPI library and will likely require a lot of work.
The inclusion filter in addition to the exclusion filter should allow much shorter filter settings in the meantime.
I've made the decision to just rewrite the code which will be tracked via #20. This will likely address this issue if this is caused by an issue in the plugin code itself.
