If you have noticed a lot of spam links appearing on your blog, web-links that you did not post, then it could be due to the plug-ins of Google chrome. Please note that this plug-ins is only seen by you on your computer, usually when you are using the Google chrome browser. So if you look at your blog from a different computer using a different browser, then you would not see these links! Also you may try using your mobile phone and check your blog from there; you will also notice that these links are not there.
Anyway if you are annoyed of this plug-ins reappearing on your blog, here is what you can do:
You can also completely disable specific plug-ins. Unlike blocked plug-ins, you won’t be able to allow the plug-in to run on a given page. When you visit a page with a disabled plug-in, you’ll see the message “Missing plug-in” appear in its place.
To disable plug-ins, visit the Plug-ins page at chrome://plugins/. Find the plug-in that you’d like to disable and click Disable. You can also re-enable disabled plug-ins on this page.
You can also reach the Plug-ins page by clicking Disable individual plug-ins in the "Plug-ins" section of the Content Settings dialogue.
