Hi Tobias,
Due to the nature of what type of plugin it is – anti-spam/security – it requires vigilance and frequent updates. It isn’t more than 1-2 updates per week at the most. Through your WordPress dashboard it’s a one-click update so hopefully that’s not too much trouble.
You don’t necessarily need to update the plugin the day the new release comes out. It’s a good idea though.
Eventually I plan to add a feature where the plugin can download certain updates from our server, but due to www.ads-software.com plugin rules, plugin developers can’t do what you’re asking without having users specifically opt in, and for feasibility it will probably have to be a premium level feature. We likely wouldn’t be able to provide automatic updates for free due to development and server costs. Keep in mind the plugin has a LOT of users. (If you notice, the plugins that do what you’re asking require a paid subscription.)
I hope that helps answer your question.
– Scott
