I want to disable the function reblog because too many reblogs are getting annoying. I saw that you can disable it with -My Sites -Tools -Marketting, but i only have -Import -Export -Delete Site as options under Tools.
Am i looking at the wrong place ?
Yes, if you decide you would rather not offer the option to reblog your post, you can disable the button by navigating to My Sites → Tools → Marketing. Then click on the Sharing Buttons tab.
Disable Show reblog button under Reblog & Like and the Reblog button will no longer appear on your blog posts. Likewise, if you later decide you would like to offer users the option to reblog your content, you can enable the feature.
