What kind of spam protection were you thinking of?

If you want to block bots from doing anything on your site, then I have to tell you that there is no reliable way of identifying bots (that I know of) and thus, no way of generally blocking them. It is also bad, well, if you block google bots and the like. If you want to prevent spammer bots from registering, then common ways of doing that is for example with Captchas and with email activation links. If you want to prevent spam content, then this is a totally different matter. Roughly, you can block links to forbidden content like porn, violence etc. in your content, but this is in no way an intelligent behavior. Once spammers decide to change their game, you must adapt as well, thus, it is a neverending race...

Personally, I am fairly new to Laravel, so I can not tell you what there is available in Laravel and Laravel packages, respectively. But I have some experience with spammers on other CMS and Wikipedia sites. I suggest you clarify your request first and then I am sure that the Laravel pros will also have the one or the other word.

I'm asking about spammer bots from registering, or leave comments etc. Yeah most useful solution it's - captcha, but i'm didn't found any for laravel5. And what about Honeypot method? As far as he reliable? Laravel has a big comunity, I'm interested which method use the most of laravel developers, if don't look for third-party API?

Just in case you have not checked: http://packalyst.com/packages/tag/security

There are many Captcha packages available. I personally prefer QuestionCaptcha with questions regarding the topic of your site. Spammers and spammer bots do not like to work and thus, do rarely adjust their bots to register on such sites. Once you get again fake account creations, you simply change the set of Q & A.

And on my current project, I use the Sentry authentication package. https://cartalyst.com/manual/sentry/2.1
