Introducing DEVIL (Detection and Exclusion of Vulgar and Improper Language) API

Are you in the lead generation business ? Leads containing profanity are most likely spam leads. They go undetected coming from clean IPs with valid content. Since they go undetected, they unfortunately make it to your recipient and do much harm to the trust and thus your business. At Dilli Labs LLC, we advice that you validate your lead content for profanity using our following API and prevent sending the lead to your recipients if the lead contains vulgar keywords. DEVIL (Detection and Exclusion of Vulgar and Improper Language) is a simple profanity filter REST API for developers that determines whether text contains profanity or not.

How DEVA validates an email address?

  • Format Validation: DEVA ensures that an email address has a valid format. Ex : validusergmail.com is invalid email address because its missing the ‘@’ before the domain ‘gmail.com’.
  • MX Records: An email address with a domain that does not have an MX record in its DNS settings is invalid. Ex: user@domainWithNoMXRecord is invalid. DEVA finds if MX records exists for the domain tied to an email address. If no MX records exist, the email address is reported as invalid.
  • Disposable Email Address: DEVA maintains a list of throwaway/disposable email addresses or junk collector email addresses and validates emails against this list. Ex : user@0-mail.com will be invalid.
  • ESP (Email Service Provider) Grammar Rules: Ex : @yahoo.com emails cannot have user part less than 4 characters. We learn new ESP grammar rules every now and then and incorporate into our validation algorithm.
  • Spam Email Address detection: DEVA has access to a gigantic third party database of email addresses known to spam. It queries this database to determine the validity of an email address. Ex : aanetaegooglety@gmail.com is one such email address that is known to spam.
  • Profanity Check: This is a distinguishing feature of DEVA. It checks email addresses for profanities and marks them invalid if found.
  • Role Based Email Address detection: DEVA detects generic group role based email addresses like info@, support@, store@, etc and marks such email addresses as invalid. (This is an Optional check and turned off by default)
  • Patterns: There are countless patterns we discovered while validating over 50,000 emails every month for our clients that are obviously invalid emails. Ex : jondoe@gmail.com, foobar@gmail.com, noemail@gmail.com, etc. DEVA is constantly learning and building up the black listed patterns as our user base grows.
  • Blacklisted Domains: Ex: example.com is reserved and can’t be used in practice. Therefore, all emails having this domain are marked invalid by DEVA.
  • Safe Domains: If the domain represents an adult site, the email is treated as invalid. (This is an Optional check and turned off by default)
  • Custom Blacklist: You may request certain valid domains, emails and users to be blocked. For example: A site may never want any mail.ru email address to be used on their site due to the higher probability of it being a malicious email address. We can add such custom requests to your validation.
  • Custom Whitelist: You may request certain known valid email addresses to be whitelisted.
  • Unsolicited Marketing: Ex: *seomarketing*@gmail.com. Many online marketing companies leverage contact forms on websites to send solicitations for business. We maintain a list of email addresses and patterns in email addresses used in such unwanted offers. (This is an Optional check and turned off by default)

Note: You may request to disable any of the above filters when validating with DEVA.
