Summary
Identifying spammers involves a multifaceted approach considering profile details, registration behavior, email content, sending patterns, list acquisition, and technical indicators. Spammers often provide minimal profile information, use free email addresses for registration, and create multiple accounts from the same IP. Their emails exhibit poor grammar, pushy sales tactics, deceptive subject lines, and a sense of urgency. They lack transparency, provide vague information, and may make unusual requests. They also tend to neglect list hygiene and acquire lists unethically. Technically, they may use shortened URLs, lack personalization, send from IP addresses on blocklists, and include suspicious attachments. Recognizing these patterns helps in identifying and mitigating spam.
