In this style, many of Malayalam captchas are too difficult to read, 
infact only some images are readable ( 
image_d3e539c0_f856b4c90b2ceeeb.png etc are some of the difficult 
ones). The image - image_5dbc3fc3_0e1a119f02c122b8.png - (ാനിതംബം)  
using a vowel sign in the beginning of the captcha, which is not common 
and almost impossible to type in most transliteration keyboards. The 
word നിതംബം after vowel sign ാ exactly means 'buttocks'. BTW, the word 
ലിംഗം repeated couple of times in images, which means 'sexual organ'.

In the image - image_b5d2be0d_7223dc2282b35e15.png -, readable part is 
problematic (last letter is not recognizable). In the readable part, 
letters appear as ച െവി where two different vowel signs are applied on 
same letter (typing probably not possible). This may be rendering 
error, which is very common in many rendering engines. Actual word may 
be (ചെവി). Same kind of problem happens in 
image_077ebd23_d890a7083e967d92.png where two vowel symbols appears 
together. It appears vowel sign ാ used independently to create these 
captchas which should be avoided.
