What will happen if I enter my number in a WhatsApp hacking website?

I don't remember the site name but when I was searching for method to hack someone WhatsApp there a site which was recommended by a lot of commentors in a YouTube video. I clicked it and that site opened it asked me to just enter a phone number. I entered my phone number and waited for few minutes and it said my to click the download the hacked content but when I pressed nothing got downloaded… So my phone is iPhone and I think they can't hack it but I'm scared that even though the site seemed safe… Can they use my phone number for some malicious work… But I don't think they can do anything with just a phone number but I'm scared will they will use my phone number for sign up somewhere in illegible activity… Or I should ignore that the site was a fake one like most…

Photos in photo vault automatically deleted?

I have a photo vault app on my iPhone (a secret app to import your important photos in with a password locked) and recently I opened it up to recheck a photo but then all of my photos that I imported are now gone. I checked everywhere on my phone and there was nothing. It was like these photos were automatically deleted without my permission to being deleted in the first place. I did not lend anyone my phone nor did I accidently clicked on something. It just poof… Gone. Any reasons? Mystery? I believe contacting support for this app would be useless.

How long will Verizon keep slowing data downloads on my iPhone 6 (for prior heavy use)?

Recently, I have not been able to stream Youtube or other videos (for music as I run) on my Verizon iPhone 6. It looks as though Verizon intentionally slows data streaming for heavy users.

Oops. I've now switched to using Wi-Fi most of the time, so I don't stream much data over Verizon's cellular network any more.

Question: How long will Verizon keep slowing my data: until the next billing cycle is over, maybe?

Rant: Verizon, you have the right to slow my data, but you should have just told me to use less, and I would have!

Continuity/handoff doesn't work anymore?

Is anyone else having this problem. My MacBook Air and iPhone 6s just stopped working with handoff. Didn't realize it before cause it didn't use it much but now that I was going to it doesn't. Does it have to do with the last update? It worked with it before. And yes Bluetooth is tuned on on both devices
