some websites blocking back button navigation in browser

recently i am finding many websites are tricking visitors not to navigate away from the website or webpage by disabling or overriding back button recently i landed up in website which offers mp3 downloads but when i did not find needed in that page when i clicked back button in the browser it was weirdly disallowing me to navigate back though i experienced this type many times but clicking back button twice or continuously for a while i was able to navigate away but this website called clip.dj was appending # at end of URL and overriding back key of browser.

below pic shows that website is automatically overriding back button by appending "#" to the same webpage URL thus making us stay on same webpage

Though sometimes it would be a legitimate redirect issue such as when you was redirected by login or some kind of transaction based navigation but if it was just a normal "search engine to website" or "webiste to website hop" and you cannot still hop back then the present website is intentionally holding you back.

So if you are stuck and you want the search engine result of the previous page then don't worry just click on the history menu from the browser and click on the previous link you came from if you know any other tip or trick to overcome this do share it here

Though i am sure its not a browser issue since i have checked this website(ex clip.dj) on IE, Chrome and firefox which is exhibiting same behavior of disabling browser back button i guess the admin/owner of the website is intentionally doing this.
