	Such links can be spoofed.

		- Can it be fed harmful values which could cause runtimes?
		- Is the Topic call an admin-only thing?
		- If so, does it have checks to see if the person who called it (usr.client) is an admin?
		- Are the processes being called by Topic() particularly laggy?
		- If so, is there any protection against somebody spam-clicking a link?
