Unread Title Clear Notice Publish in Newspaper

Dear Sir / Mam, When I am reading the Newspaper I am feeling surprise that, since several decades same kind of Title Clear notice publish when there was trend of Newspaper and today media is change like Facebook, News Channel etc. so, now in the new generation there are several people who doesn't read Newspaper either every day or even never read. Still there is written in the notice that, if there will be no objection within 7 days of this notice it will be understood that nobody has any rights in this property and even if rights exist then it will be waived off! This last sentence has absolutely no logic...! Suppose if that notice publish in Gujarat Samachar and if I subscribe Divya Bhaskar and even if it publish in my subscribe Newspaper and that day if I went out of station and couldn't read that notice then my rights on that property waived off by my side...? How this law is applicable and how everyday all advocate giving such public notice without any change as per current scenario of avoid Newspaper and change the trends...?! It never happen with me, but there is always question in my mind so, here I found that expert advocates are on this blog so, kindly revert with your opinion of this matter to increase my and other viewers knowledge. Thanking You Parag Shah
