Spam or SPAM commonly refers to: Spamming, unsolicited or undesired electronic messagesEmail spam, unsolicited, undesired, or illegal email messagesMessaging spam, unsolicited, undesired, or illegal messages in general (private messages on websites, sms, messenger etc...) Again like i said, what may be undesired or unsolicited to one, may not be the case for another.. Spam is a subjective term but you are right the simple way is to report it if one is really bothered by it, let the mods decide no reason to come and post a forum topic about it
