![]() In this way, spammers can automate the process of promoting and publishing spam.Īn example of a spam comment from a bot: How do spam bots operate on social media? Other times, bots will create fake user accounts and leave comments – and if one account gets shut down, they create another one. This is easier if the forum does not have sufficient verification for checking if a commenter is a human user, but some bots can get past those protections even if they're present. Some spam bots look for and post in comments sections that don't require a user account for participation in a thread. What is comment spam?Ĭomment spam is any spam that appears in the user-generated comments section of a website. They can purchase lists (often on the Dark Web), they can steal a company's legitimately obtained database, or they can trick users into giving them their email address. Spammers don't always use bots for collecting email addresses – they can obtain email lists from a variety of other places. Spammers may use a technique called email spoofing to make it appear like their emails come from a legitimate source. Often spam emails are criminal in nature, attempting to spread malware or steal account credentials via phishing. ![]() Once the spammers have a database of email addresses, they can then blast out spam emails. Email address harvesting is carried out by bots that scan webpages, look for text that follows the email address format (text + symbol + domain), and copy that text into the spammer's database of targets. Senders of email spam need as many working email addresses as they can find. Some spam bots harvest email addresses or phone numbers to provide targets for spammers – they scan the web, scrape contact information, and save it to a database. Other kinds of spam bots may assist spammers without actually sending the spam messages. Once spam bots have an account or otherwise have access to a platform, they will start pushing out spam messages according to a predetermined (by the bot creator) set of rules. Some platforms offer CAPTCHAs or similar challenges to prevent bots from creating accounts, but these defenses are not foolproof. Since creating a user account often only involves filling out a few fields (name, email address, etc.), attackers will program spam bots to fill out these forms automatically – a relatively simple task for a skilled programmer. Sometimes they'll try to disguise their activities as coming from a real user. Spam bots can create fake accounts on forums, social media platforms, messaging apps, or email hosting providers. Instead, spam bots spread preprogrammed messages or follow preprogrammed conversational scripts to interact with users. Users are not interacting with a real person when they encounter a spam bot's handiwork, even if the bot appears to "respond" to user interactions. Like the robocalls that have plagued many consumers in recent years, most online spam is fully automated by spam bots. Spam can also be any content that's irrelevant and delivered in large volumes. Usually, spam involves unwanted product advertisements, irrelevant backlinks (to attempt to get the linked website higher in search engine results), or more sinister things like scams or malware downloads. ![]() Spam is any inappropriate or unwelcome message that's pushed out to a large number of users. A spam bot may also post spam in various places where users interact online, such as social media platforms or forums. A spam bot is a specific type of bot that sends (or helps with sending) spam messages. Speaking generally, bots are computer programs that execute repetitive tasks, and they usually operate over the Internet.
