I thought I already explained this. Like forums have the ability to censor words like shit etc to s*** we can too. We chose not though and instead have used those to make shortcuts.
!help ______ gives you a shortcut to a link in the wiki so we don't have to go through and find links etc. So take reseeding for example we just have to type, help reseeding with an ! infront and it thinks its a naughty word so it replaces it with:
How to re-seed
A similar effect can be done here. Instead of having to find the image and repost it etc I can create censor words that will be like, '!bbtemote meanie' or '!bbte facepalm'. The forum will recognize it as a naughty word and replace it with whatever I specify. In this case it would be [img] tags and the correct url so all you have to do is type it and it will fill it out for you. Think of it as like a command line interface.
We just used !help because the likely hood of !help _____ occuring in regular speech is low and !help ______ is the same command for our IRC bot so !bbte ______ or !bbtemote ______ would have the same effect.
