It seems that somebody has been deleting my comments. In one post the comments were reduced from 15 to 10 and significantly on another post from 20 to 8 as well which I had imported from blogger. I presumed that wordpress was totally safe.
One does not expect this from a world classproduct like wordpress. If there is something wrong I am doing, please let me know.
Apart from longer passwords, what are other security measures one can take so that this does not happen. Please reply promptly. Thanks.
