Tenses out of temporal context

Two tenses most frequently abused by writers and even editors are the present continuous and the present perfect continuous tense. Copies keep coming in, or even getting in print, with sentences such as 'the government is doing this for a month,' which needs to be in the present perfect continuous tense because of the period of time, and 'the agency has been doing the work,' which needs to be in the present continuous tense because of the absence of any period or point of time to go with the verb. A glance at reports published in Dhaka newspapers even in the past shows such mistakes have kept coming in print... for years.
