I've seen people hysterically cry over having a ref link removed or even claim having their thread moved to the correct sub board is 'censorship'.
I was suspended for 3 days over the bolded, but I was not informed by any mod or staff that nuked it (no one could figure out why either when I created a thread using my alt), until days later when I noticed my thread posted under Micro Earnings (which had been running for months without any hiccups) disappeared without a trace.
However it was more to promoting my website for some passive income earnings and surprisingly it was either reported or discovered like way too late or something.
Basically if that counts as a refspam, now I know but they have to give the source (offending URL) behind the suspension. I've never refspammed prior to the incident and it somewhat caught me by surprise.
