Spam is a common phenomenon that we all struggle with in our everyday lives. Spam emails, phone calls, messages can all get a bit irritating and when you are into an online business, the inherent risk of becoming the victim of web spam risk increases. Small malignant programs–spam bots–might attack your knowledge base and flood fake information (registrations, comments, subscriptions) into your knowledge base. PHPKB knowledge management software provides spam protection to your knowledge base through different anti spam techniques.
Spam bots are automated computer programs that are built to find form code on your knowledge base and submit fake information like spam messages to your forms. Spam bot attacks like email spam etc, significantly damage your reputation and reduce your delivery rates.
Spam bots affect your knowledge base in following ways:
Fake subscriptions in your knowledge base would increase in spam complaints, bounces and unsubscribes, and decreased open rates. Spam bots generally use real email addresses without the owner's permission or knowledge and that results in junk email in users inbox. This leads to low open rates which shows that your recipients are not engaged with you, your brand, or your content. Lack of engagement is a factor in the delivery of future emails, and can even lead to your messages being blocked and increased bounce resulting in a mail server rejecting or blocking your emails entirely.
Illegitimate comments would engage all your users (new or old) in filtering the good content which will annoy them and may even stop them visiting your knowledge base altogether, affecting your brand reputation and revenue.
Fake Sign-ups are capable of making it a task for the businesses to reach out to their genuine customers, resulting in an attack on its own brand image.
Spam bots can generate fake support requests resulting in unwanted emails for customer support executives, which would engage them unnecessarily in addressing queries that will not yield any profit to company.
Unwanted bot traffic can slow down your knowledge base and increase bandwidth costs. When millions of bots spam your knowledge base with requests, your knowledge base takes longer to load. Slow pages frustrate users which can affect your brand image as your users may go to competitors’ websites.
In conclusion, spam impacts the credibility of your business, and eventually hurts user retention.
