Most of what you reported is not spam. If you don't like boosting, filter it using CCleaner. Selling boosts for gold is not against the ToS. The 2 or 3 legit spammers will be blocked next update.

Guild spam is low priority, you can report on the Guilded ticket tracker and I'll get round to it when I have time. The addon filters ~90% of guild spam, I am happy with this number.

They are both already blocked in the new update.
