Many users mention to use report to moderator button, I disagree since this button doesn't work when you report a post in less moderation sections. As long as you're not post in a row, commit plagiarism, using AI, one liner post, share refs link, or begging, your post high likely will not be deleted.
Ignore the users who is having the only intention of trolling and for that ignore option is really helpful but to tackle spammers report to moderators should be the tool, and if the user is having this as habit then eventually they will be in the risk of getting temp banned at least for multiple deleted reports for spam as reason.
Ignore isn't solving the case.
There are many times has been mentioned spammer would get temporary banned, the question who's the user that get temporary banned due to spam in the past 2 years?
