Is ECI voter data being leaked to political parties?

Hyderabad:  Controversy seems to be the leitmotif of the Election Commission of India (ECI). After earlier facing flak for mass name deletions, questions are being raised if the ECI’s data of voters is being leaked to political parties, especially the Bharatiya Janata Party (BJP).  Citizens from Hyderabad, who enrolled as voters for MLC elections (Graduates constituency) have been stumped as to how they received congratulatory messages after their names were successfully registered as voters. At least half a dozen citizens took to Twitter and posted screenshots of messages they received from BJP leader N. Ramchander Rao.  “I am extremely delighted to inform you that you have been successfully enrolled as a voter on the rolls of the HYD-RR-MBNR graduates MLC constituency. Looking forward for your support and blessings to give me another opportunity to work for better society,” stated the automated message from Ramchander Rao.  Many have raised questions as to how and why the BJP managed to get hold of such data. While political parties do have access to electoral rolls to verify voter data, how phone numbers have been accessed does raise questions.
“I registered for MLC voter lists in Telangana and I get a message from the BJP Floor Leader about my successful enrollment. How are my details shared with BJP @ECISVEEP?” questioned city-based activist Srinivas Kodali on Twitter.  His tweet got about 1,300 likes and nearly 600 retweets. Responding to his tweet, other users also shared screen shots of the same. When asked if other political parties also have access to such information, Congress and Telangana Rashtra Samithi (TRS) functionaries replied in the negative.
