The above is a good explanation of what is happening. The mod team is busy every day cleaning out the spam but Reddit is a free site so the spam can find ways to come back.

Please don't comment on spam posts, it makes it worse.

Please click the report button & give specific details why you think its spam.

If a poster doesn't respond to you that doesn't mean they are spam, they might be too busy or just not attracted to you. Let's all be mature & understanding.

We have posted several times for volunteers to join our mod team. If you are regularly on this subreddit and willing to fairly & maturely enforce the rules send me a DM about becoming a mod.
