I said I used this but once in the title - I meant: I will use it again.
Have success! Thank you for your review.
Hi Chris, before making this review without any information and without any useful goals, please see:
Every input field on your site of course needs to be protected (guestbook, forum, contact) so set the guestbook right way.
What you mean with backdoors?
As written everywhere. IF YOU OR ANYBODY ELSE KNOWS THE BACKDOORS IN Phoca Guestbook, then just let me know. I WILL BE THE FIRST WHO WILL APPRECIATE SUCH information and will fix it. But until know, everybody is speaking about "backdoors" but nobody has any idea what exactly is the backdoor.
On Phoca Forum, you can see, that most of case, the problem was not by the guestbook itself but by other parts on the server, etc.
Of course, one of the method how to add a spam to the site, is through human spamming. But there is no protection for human spamming. If you have site with input fields, you will allways get such type of spam. I get every day over 50 human spams in my forum. I will never write a review of phpBB that it is not good software :-(
Thank you for understanding.
Always use plain text - never, never copy e.g. a link out of an HTML mail, because that would insert unwanted elements (anchors and things) to the QRCode generated, therefore rendering it unusable!
Unwanted elements are added by WYSIWYG editors.
