I've been testing the Aria bot for a couple of days now and I've realised that it is very limited and lacks a lot of features to be considered 'promising'.

One of those things it lacks is the ability to dismiss alerts based on simple keyboard spacing, something that Bing does (no matter how many times you press it, it doesn't allow you to send it as an alert), this would avoid collecting similar messages.

The same would be true if other types of inputs with signs and symbols were avoided, and only those accompanied by a certain context (be it a mathematical function, a quote/phrase or a code) were allowed.
