What is a TextCHA?
It is a pure text alternative to CAPTCHAs. MoinMoin uses it to prevent wiki spamming and it has proven to be very effective.
Features:
- for page save, ask a random question
- match the given answer against a regular expression
- q and a can be configured in the wiki config
- multi language support: a user gets a textcha in his language or in language_default or in English (depending on availability of questions/answers for the language)
Tips for answering:
- you need to answer the textcha for e.g.:
- page save
- attachment upload
- user profile creation
- you do not need to answer the textcha for e.g.:
- page preview (if you do, it will remember what you entered, though)
- user profile changes
- it is usually a simple/short answer
- it compares case-insensitive
- sometimes you can find the right answer by reading some important pages of the wiki
