Multiple clicks in email

Hi,

We notice from time to time that some leads will click a link in an email multiple times in a short space of time, eg 4 clicks on the same link in 5 seconds.

Does anyone know that this might be? I find it hard to believe that someone would be clicking an email link that many time at once unless its not loading and they are extremely impatient. Or is it a case of this being a bug?

Any insight would be helpful.

Thanks

Natali
