BlockBot has an excellent memory despite her old age, and this has apparently been causing some problems. For example, imagine this situation:
- You join the IRC, say "hi" and go play Blockland, then get off the computer.
- You open Blockland again, join the irc and say "hi" and BlockBot will think you're spamming.
All she's really seen you say is "hi" twice - she doesn't really care about when you leave/join the irc. I'll have to have words with her about this, but for now I suggest you just mix up your greetings.
