This is your only warning. The next time you insert a spam link, as you did to Uninterruptible power supply, you will be blocked from editing Wikipedia. Spammers may have their websites blacklisted as well, preventing their websites from appearing on Wikipedia and other sites that use the MediaWiki spam blacklist at all.
