just hit the ignore button if you dont want to read anything from him.
and to get back on topic: referrals are spammy. download links are often useful. hence i support the former to be forbidden ;-)
Don't want to ignore him as his comments make me laugh a bit

I just want to understand how can posting referral link in OP be spammy and posting link to download something be not spammy ? I am looking for logical reasons not "what you/I/admin thinks"
