| I occasionally notice some spam accounts being created on my Mastodon instance. If they haven't posted to the timeline then they generally aren't spotted/reported and the only way I can see them is to manually review new accounts when they sign up. On those rare days that there is a massive spike in signups (we had 11k sign up to https://glasgow.social over a few days in November) it's just not feasible to manually review. I made this script to let me review the accounts after the fact (this also helps catch those spammers who create the account, wait a few days, then modify them). | I occasionally notice some spam accounts being created on my Mastodon instance.

| + | I added a moderation link to the CSV output so I can just open that file in a browser with this for example: | ||
| + | <code bash> | ||
| + | php scan_for_spammers.php | grep -E "^4" > output.html | ||
| + | </code> | ||
| + | |||
| + | To answer a question on Mastodon; You could add a list of spam keywords or suspicious urls at the top of the file, for example: | ||
| + | |||
| + | <code php> | ||
| + | $spam_keywords = array('spam_term', 'spamwebsite.com'); | ||
| + | </code> | ||
| + | |||
| + | Then add a loop just after the ''foreach($attachment..'' to search the profile text for a url or keyword, for example, adding this would increase the score generated based on more keywords matching: | ||
| + | |||
| + | <code php> | ||
| + | foreach($spam_keywords as $keyword) { | ||
| + | if(preg_match("/$keyword/i", $json['summary'])) | ||
| + | $score++; | ||
| + | } | ||
