For minimizate spam my idea is use a type of filter when register , making 3 o more scientifics questions:
Example : If concentration hydrogenions is 4.3 exp -10 which is Ph?
chorhydric acid + calcium hydroxide =
etc etc,

My question is whether these are targeted or random? If they are random, it might benefit to play around with the registration page a bit so that the
bots can't auto-fill the form as easily.

The program the spammers use is xrumer
Wikipedia article how to combat it
Webmasters of topical forums face an ongoing battle against XRumer software, users of which are almost always in violation of forum terms of service,
and/or have no interest in the actual forum topic. The users of the software have created an entire industry whose sole purpose is to protect internet
sites against users of XRumer. Forum administration tasks against XRumer are often a constant, daily effort, which include identifying new user
accounts that are from XRumer users, deleting posts/threads created by the software, and deleting/disabling the user accounts.
The easiest method to defeat Xrumer is to simply require the first post of any new forum member or blog poster to be approved before it can appear.
There are several resources that help block forum spam, which reference reports of forum spam by username and IP address. If a user/IP has appeared in
the site's lists, it is highly likely that it is a black-hat user of XRumer. Common defensive actions by webmasters are to institute IP-based posting
bans on subnetworks used by the spammers.
The spam messages in a forum typically take the form of "link spam" which will often be included in older topics and private messages (PMs) leaving
the newer threads and posted messages "clear" of apparent spam. Sophisticated spammers will copy posts from other areas of the site, giving the
appearance of a valid, on-topic reply. The best clue that it is a spammer is that the links in the user profile are completely unrelated to the forum
topic, and the posted messages, while seemingly within the general topic of the forum, will be non-sequiturs and out-of-place within the topic thread.
Alternatively, the spammers post generic "I am excited to begin posting and contributing here." messages that are content-neutral.
They arnt that smart
The damage caused to forums is classified in several areas: first, and foremost, the admin time to clean the forum. Second, the server bandwidth to
accommodate the spam postings, third, the storage requirements at the forum server for the spam messages that are devoid of content, fourth, the
alienation and irritation about seeing spam by the forum community, fifth, the offense to innocent forum members if their posts are mistaken as spam
or their accounts suspended in error for suspected spamming, and sixth but perhaps the most important, the lowering of the information-to-noise ratio
of the forum, which diminishes the value of the forum, skewing usage/active user statistics
