You must be cautious while answering number of seats and percentage requirement type of answers. Seats seems piece of cake, but requires a good research. And 55% doesn't fits everywhere.
There's no limit on number of points one can score in a day or number of answers one can post in a day.
In order to avoid Bulk Posting, one has to adopt the natural method of answering - Reading > Understanding > Doing research (if applicable) > Typing the answer > Hitting the submit button > Content uploading starts and only that particular instant of time when it is successfully uploaded and redirects back, is recorded as the time of post. Now, you can proceed towards the next question.
One should not do something like- Opening several tabs > Type answers in each of them taking several minutes to research and type. Now, start hitting the submit post button one by one after every 2 minutes. This causes a rapid increase in individual's points on the ranking page, as a result other rankers feel devastated, demotivated, cheated and feels that partiality is being done by the forum management.
Forum software is considering you a Spammer that's why blocking your posts. Please, avoid URLs, Colour, Bold/Italic, etc. in your answers. Simply post 5-10 plain textual answers (but not 1-2 liner, rather descriptive). Once all of your answers are approved, this error will go away.
