Dear sirs,

Last  time  I'm  receiving  a  lot  of  spam  to my RIPE contact
email.

I have a suggestion that will probably help to reduce spam to emails
provided in RIPE whois output:
1. Substitute email addresses in whois output with something like "use
http://www.ripe.net/whois";

Replacing an email address with an HTTP URL is good. (Although just today I got a spam via my web form; but that is so inefficient for a spammer, it's rarely used. How flattering that they bothered. Heh.)

2. Substitute letters in emails at http://www.ripe.net/whois with
their graphical representation or use javascript to build the text
that spam robots will be unable to parse.
3. Add following text to your whois web-engine: "You need
javascript-compatible (graphics-compatible) browser to see emails".

Locking out text-only browsers like Lynx is bad.

There are many ways to text-munge an email address. For example:
tldcomdommicrosoftusrbillg or billg [at] microsoft [dot] com
A human can figure that out easily but it'll just look like a random string to a spambot. The encoding format could even change at random intervals.
