Php, jQuery, js
What if in a car dealer site appear telephone of owner, what ways exist to hide the tel - may is mobile number - from non humans to avoid any kinds of bad usage,… like spam, … etc??
You would need some reliable form of CAPTCHA to access the number.
Many methods would have accessibility issues.
If using sthg like
tel: click to appear,
and tel saved in sessionStorage…
Search engines read session or local storage??
No I don’t think they can read session data, but neither can real visitors, so at some point you need to display that data, then it becomes readable to both people and robots.
Captcha is the only method I can think of right now that would be accessible. The problem being that people may not like having to “jump through hoops” to do something as simple as view a phone number, it may put people off.
I can think of other methods, but they would not be good for accessibility.
I meant click and load via JS the tel number from session storage or local storage, well?
Yes, bots can easily do that.
